INTRODUCTION
Service Information S28O-4O-8 provides the maintenance
instructions for Type RVE and WVE three-phase, electronically
controlled, oil reclosers. Included is a general description of
the recloser and its operation, instructions for periodic inspec-
tion and routine maintenance, testing procedures, and instruc-
tions for shop repairs. A service parts list, keyed to exploded-
view drawings of the recloser is included at the back of the
manual.
Procedures for testing the recloser and control together are
found in the control installation manual S280-75-1.
DESCRIPTION AND OPERATION
General
The Type RVE and WVE reclosers, are self-controlled devices
that protect distribution lines and equipment. A complete unit
consists of the recloser, a Type ME electronic control, and an
interconnecting cable. Fault current sensing is provided by the
control which actuates the recloser. Circuit interruption is pro-
vided by the recloser.
The Type RVE and WVE reclosers trip open an overcurrent
(either phase or ground faults) and then reclose automatically.
If the overcurrent is temporary the automatic recloser restores
normal service. If the fault is permanent a preset number of trip
and reclose operations are performed to lockout. All three
phases of the RVE and WVE reclosers open, reclose and lock-
out simultaneously.
Opening sequences can be all fast, all delayed, or any com-
bination of fast operations followed by delayed operations up to a
total of four. Fast operations clear temporary faults before
branch-line fuses can be damaged. Delayed operations allow
time for fuses or other downline protective devices to clear so
that permanent faults can be confined to smaller sections of line.
Fast arc interruption is provided by bridge-type contacts which
provide two breaks in series per phase. Each current break has
a self-generating type arc interrupting structure with a series of
vented chambers. As the contacts open, the arc generates gas
pressure within the interrupting chamber which blasts oil across
the arc and out through the vents. The moving bridge-type con-
tacts are driven by the release of opening springs that are load-
ed when the recloser mechanism is closed.
Closing energy, as well as energy to charge the opening
springs, is supplied by a high-voltage closing solenoid momen-
tarily connected phase-to-phase through a high-voltage contac-
tor. The contactor is mechanically closed by a rotary solenoid
actuated by a signal from the electronic control.
A trip-free, yellow operating handle located under the sleet
hood will manually lock open the recloser. It cannot manually
close the recloser but must be in the CLOSED position for the
rotary close solenoid to operate. A red contact position indicator
linked to the recloser mechanism, but independent of the operat-
ing handle, is also located under the sleet hood.
The location of the major operation components of the RVE
recloser is shown in Figure 2. They are similar for the WVE
recloser. Being aware of the location of these components and
their part in the operation of the recloser will give a quicker and
clearer understanding of the recloser maintenance and repair
procedures that follow.

DUTY CYCLE
MECHANISM OPERATION
The head mechanism performs the actual opening and clos-
ing operations in response to signals from the electronic
control. Contact opening is initiated by a trip coil. Contact
closing is performed by the closing coil, mounted below the
mechanism. The basic operation of lever arrangement is
shown in Figure 3.
With the contacts closed (a) the opening springs are fully
extended. The trip coil push rod rests up against the toggle
latch and when the trip coil is energized, the toggle opens
(b). The contact-and-toggle-support assembly and the con-
tact-and-trip-arm assembly rotate on their shafts and begin
to push the contacts open. As the opening springs rotate the
contact-and-trip-arm assembly past this point (c), the trip
arm moves the
reset trip lever, which releases the reset lever. The reset lever is
rotated by a spring and snaps the toggle closed. This motion of
the reset lever also pulls the plunger out of the closing coil. At this
point the contacts are completely open.
The closing coil is energized by a signal to the rotary solenoid
on the side of the mechanism. The solenoid closes the closing
solenoid contactor, which energizes the coil. The plunger is drawn
into the coil and the reset lever is pulled back (d) to its original
position, at the same time closing the contacts. The mechanism is
then ready for another cycle.
MAINTENANCE
Frequency of Maintenance
Because reclosers are applied under widely varying operating and
climatic conditions, maintenance intervals are best determined by
the user based on actual operating experience. To assure proper
operation, reclosers must be maintained when they have operated
the equivalent of a complete duty cycle and before the dielectric
strength has deteriorated below prescribed levels. In the absence
of specific operating experience, the following procedures are rec-
ommended.
•When Type RVE and WVE reclosers are operated under usual
service conditions as defined in ANSI (American National
Standards Institute) C37.6O, “Standard Requirements for
Automatic Circuit Reclosers for Alternating Current Systems,” it
is recommended that the following maintenance procedures be
performed at the completion of an equivalent duty cycle.
NOTE: ANSI C37.61, “Guide for the Application, Operation and
Maintenance of Automatic Circuit Reclosers” gives a procedure for con-
verting the standard duty cycle, as shown on page 3 of these instructions
into an equivalent duty cycle based on the actual operating duty of the
recloser.

Types RVE and WVE Maintenance Instructions
85693KMA
•However, if the recloser has not completed an equivalen
duty cycle within three years, it is recommended that an
external inspection, oil-level check, and a check of the
dielectric strength of the oil be made at that time. (See
steps 1, 2, and 8 of “Maintenance Procedure” below.)
Periodic Maintenance Inspection
Each periodic maintenance inspection done at the completion
of an equivalent duty cycle, should include:
1. Bypass and remove the recloser from service.
2. Inspect external components.
A. Check for broken or cracked bushings. Replace as
necessary (see page 6 for procedure).
B. Check for scratched paint, repaint as needed.
C. Note counter reading and enter in the record log.
3. Perform an insulation level withstand test (see page 6 for
procedure).
4. Raise head mechanism assembly from tank to expose
internal components.
CAUTION
Be sure the recloser is open (yellow operating handle
down) before raising the head mechanism assembly so the
mechanism can not be accidentally tripped while out of oil.
Tripping the mechanism out of oil can damage it.
CAUTION
Arc interruption in oil under normal operating conditions may
cause an accumulation of volatile gases under the head of
the recloser. Untank the recloser in a well-ventilated area
away from open flames, sparks, or lighted smoking materi-
als. Be sure to ventilate the recloser thoroughly.
CAUTION
Never use volatile solutions, detergents, or water-soluble
cleaners.
5. Clean all internal components.
A. Remove all traces of carbon by wiping with a clean,
lint-free cloth.
B. Flush the mechanism with clean transformer oil.
6. Remove the moving contact assembly from the bottom of
the contact lift rod to check the erosion of the contacts.
A. Arcing tips of the moving contacts can experience con-
siderable erosion before replacement is necessary.
Slight pitting and discoloration can be dressed with a
piece of crocus cloth.
B. However, erosion of the load current carrying contact
surfaces requires replacement of the entire internal
structure before its effectiveness is impaired.
C. Figure 4 shows a moving contact after it has experi-
enced severe interrupting duty and a new one for com-
parison. The used contact has reached the condition
where it should be replaced.
7. Check circuit components attached to the recloser head,
frame and operating mechanism.
A. Check condition of the wiring to the terminal strip and
make sure all connections are tight.
B. Make sure that the rotary solenoid and the trip solenoid
are firmly attached to the recloser frame.
C. Check that the two mercury switches are securely held
in place by the nylon mounting straps.
D. Check condition of microswitch mounted above main
shaft.
E. Check condition of the bushing current transformers and
the associated wiring.
F. Check the control cable receptacle. If circuit component
malfunction is suspected, see page 12 for an operational
check procedure.
8. Check the dielectric strength of the insulating oil.
A. An oil sample taken near the bottom of the tank should
have a dielectric strength of not less than 22 kv rms.
B. Low dielectric strength indicates the presence of water or
carbon deposits. Replace the oil as necessary.
9. If oil must be replaced.
A. Drain the tank, and clean out all sludge and carbon
deposits.
B. Fill with new, clean, insulating oil up to 2-1/4 inches below
the top of the tank flange. Tank capacity is approximately
41 U.S. gallons. See Oil Condition on page 6.
10. Clean and examine the head gasket. Replace if it is cracked,
cut, or otherwise damaged, or if it has been permanently
deformed.
11. Clean the head gasket seat and retank the recloser.
A. Move the yellow operating handle to the up position to
avoid any possible binding while retanking.
B. Replace the head bolts and tighten to 35-55 ft-lbs. torque.
Apply clamping force gradually and equally, in rotation, to
each bolt to achieve an evenly distributed gasket sealing
pressure.
12. Check the oil level with the dipstick in the head and adjust
the level to the upper line on the dipstick.
NOTE: If the recloser is equipped with an oil-sight gage, the oil level
should be above the sight gage. If the oil surface line is visible in the
window, add oil to raise the level to the upper line on the dipstick
13. Repeat the high voltage dielectric withstand test (Step 3) to
make sure the dielectric clearances within the tank have not
been compromised.
Manual Operation of the Recloser
The recloser may be closed and opened manually while the
mechanism is either in or out of oil.
MECHANISM IN OlL

D. Turn the closing tool one-quarter turn clockwise to close
the main contacts.
CAUTION
Never use the KA90R closing tool to close an energized
recloser. Forcing the tool beyond the mechanism stop may
shear the pin on the closing shaft.
CAUTION
The mechanism may be damaged if it is "quick-tripped"
with the yellow operating handle while out of oil.
2. To open the recloser.
A. Pull down the yellow operating handle to trip open the
recloser.
MECHANISM OUT OF OIL
To operate the mechanism out of oil, proceed as follows
1. To close the recloser.
A. If the mechanism is still mounted in the head use the
procedure for a tanked recloser above (Mechanism in
oil)
B If the mechanism is removed from the head turn the
trip-reset shaft (Figure 6) with a pair of needlenose pl
ers to reset the mechanism, then turn the closing shaft
clockwise with the closing tool to close the main con-
tacts.

Insulation Level Withstands Tests
High-potential withstand tests provide information on the
dielectric condition of the recloser. Testing is performed at
75% of the rated low-frequency withstand voltage 52.5 kv.
TEST 1: Proceed as follows:
1. Manually close main contacts of recloser (see page 5 for
procedure).
2. Ground recloser tank and head.
3. Connect all three source-side bushings (1, 3, 5) together.
4. Apply proper test voltage to source-side bushings.
5. The recloser should withstand the test voltage for 60 seconds.
TEST 2: Proceed as follows:
1. Manually close main contacts of the recloser (see page 5
for procedure).
2. Ground recloser tank and head.
3. Ground Phase A (bushing 2) and Phase C (bushing 6).
4. Apply proper test voltage to Phase B (bushing 3).
5. The recloser should withstand the test voltage for 60 seconds.
TEST 3: Proceed as follows:
1. Open main contacts of recloser (see page 5 for procedure).
2. Ground recloser tank and head.
3. Connect and ground all three load-side bushings (2, 4, 6).
4. Connect all three source-side bushings (1, 3, 5).
5. Apply proper test voltage to source-side bushings.
6. The recloser shouId withstand the test voltage for 60 seconds.
7. Reverse the connections: ground source-side bushings (1,
3, 5); apply test voltage to load-side bushings (2, 4, 6) for 60
seconds.
8. The recloser shouId withstand the test voltage for 60 seconds.
TEST RESULTS: These high potential withstand tests provide
information on the dielectric condition of the recloser and the
integrity of the interrupters.
A. If the recloser passes the closed-contacts tests (Tests 1
and 2) but fails the open-contacts test (Test 3) a deteriora-
tion of one or more of the interrupters is likely to be the
cause. Check each interrupter individually to determine the
failed phase or phases, and replace the interrupter(s).
Retest to confirm the repair.
B. If the recloser fails the closed-contacts tests (Test 1 and 2)
the cause is likely to be adiminished electrical clearances,
low oil dielectric strength or failed insulation. After correct-
ing the problem, retest to confirm the repair.
Oil Condition
Oil provides the internal insulation barrier between phases and
from phase to ground, and must be replaced before it deterio-
rates below a safe dielectric level. Replace the oil if its dielec-
tric strength falls below 22 kv.
New oil should always be filtered before use even though it
is obtained from an approved source. Passing the oil through
a blotter press will remove free water and solid contaminants
such as rust, dirt, and lint. Keep aeration to a minimum during
filtering to prevent moisture in the air from condensing in the
oil and lowering its dielectric strength.
Used oiI must be treated before reusing. FiItering may
remove absorbed and free water and other contaminants to
raise the dielectric strength to acceptable levels. However, fil-
tering does not always remove water-absorbing contaminants
and the dielectric strength may fall rapidly after being returned
to service. Therefore the recloser should be filled with new oil,
or oil that has been restored to like-new condition. oil used in
these reclosers conforms to ASTM Standard D3487, Type l; its
property limits are shown in Reference Data R280-90-1, “Oil
Specifications and Tests.”
RATING CHANGES
The continuous current rating and minimum-trip values can be
changed in the field, refer to the control installation manual for
applicable procedures.
Closing coils are available in various voltage ratings from 2.4
to 34.5 kv. There are also three dc closing coils available: 48,125
and 250 vdc. No coil fuses are used with the dc closing coils.
When converting a recloser from a high voltage closing coil to
a low-voltage closing coil a low-voltage contactor and coil kit
(KA887R) is required.
ADJUSTMENTS
Control
Refer to the control installation manual (S280-75-1 ) for applica-
ble procedures for adjusting operations to lockout, reclosing
time, phase-trip sequence, minimum-trip values, resetting time,
ground-trip sequence, phase-trip timing and ground-trip timing.
CONTROL LEVER OVERTRAVEL ADJUSTMENT
Check for proper adjustment of the control lever by first removing
the sleet hood cover to expose the control lever. From the OPEN
position, slowly push the control lever toward the CLOSED posi-
tion. As the lever is pushed up, latching of the recloser will be
felt. At this point the dimension between the top of the control
lever and the underside of the sleet hood should be 1/4 inch
(Figure 8).
If the control lever is not adjusted properly, remove the C-ring
and slide the control lever from the shaft. Rotate the control lever
clockwise to reduce the dimension or counterclockwise to
increase the dimension. Slide the control lever back onto the
shaft and recheck the dimension. When the proper dimension
has been obtained replace the C-ring.
SHOP MAINTENANCE PRODEDURES
The operations described in this section should be performed
under the cleanest conditions possible. The repair work, except
for bushing replacement, will be simplified if the work bench is
arranged so the mechanism/head assembly can be inverted
(bushings down). No special tools are required for any of the
repair procedures.
Bushings
Bushing maintenance generally consists of a thorough cleaning
and a careful examination for chips, cracks or other mechanical
damage during the periodic maintenance inspection. Bushings
must be replaced whenever damage is discovered. Refer to
Figure 9 and proceed as follows:
1. Disconnect the bushing lead from the bottom end of the
bushing rod.

3. Remove the three hex head capscrews and clamps that
secure the bushing to the head and pull corona shield and
clamp off bottom of bushing as it is lifted out.
4. Remove and discard the lower bushing gasket.
5. Twist off the split aluminum clamping ring from the old bush-
ing and install on the new bushing, if it is in good condi-
tion—replace if damaged.
NOTE: The clamping ring cushions and distributes the pressure
between the ceramic and the clamps DO NOT OMIT.
6. Install the new bushing through the head and slide corona
shield and clamp over bushing.
7. Position bushing with the stud end of the terminal pointing
outward.
8. Position the clamping ring with the split centered between two
clamping bolts.
9. Reassemble the bushing to the head casting. Tighten the
bolts evenly, a little at a time, to a torque of 10-15 ft-lbs.
NOTE: Clamping forces must be applied gradually and equally in
rotation to each bolt. This results in an evenly distributed gasket
sealing pressure.
10. Install corona shield O-ring into groove on bushing.
11. Slide corona shield down so inside edge is flush with mecha-
nism frame. Position clamp approximately 1/4” above edge
of the shield and secure tightly.
12. Reconnect the lead to the bushing rod.
Interrupter Assembly
1. Using a 1/2-inch thin wall socket, remove the vibration-proof
hex nut that secures the contact yoke to the lift rod. Gently tap
contact arm to remove contacts from the lift rod.
2. Remove the terminal bolt from the top of each stationary con-
tact assembly.
3. Remove hex nuts, flat washers, and lock washers that secure
the interrupter assembly to the stringers.
4. Slide the arc interrupter assembly (Figure 11 ) off.
NOTE: The arc interrupter and contact assembly and the moving con-
tact assembly are both replaced as assemblies. They should both be
replaced at the same time.
5. Place the replacement interrupter assembly into position and
secure it with original hardware.
6. InstalI the terminal bolts into each stationary contact assembly.
7. Place the movable contact assembly onto the lift rod and
install a new vibration-proof hex nut.
NOTE: It is recommended that vibration-proof nuts not be reused.
Closing Solenoid Contactor
If the contacts are badly burned or eroded, the entire contactor
must be replaced. See Figure 12 and proceed as follows:
1. Unhook the two toggle openings from the pin that connects the
operating shaft of the contactor to the toggle arm.

2. Remove the three C-type retaining rings and withdraw the
pin.
3. Disconnect the two coil leads from the contactor.
NOTE: Reattach the lockwasher and hex nut to the contactor termi-
nal immediately after disconnecting the coil lead to prevent loss of
moving contact parts which are attached to the support plate with
the same hardware.
4. Disconnect the two fuse leads from the contactor.
5. Remove three hex head capscrews and lockwasher that
attach the contactor to the underside of the recloser mech
nism frame and remove contactor.
6. Install the new contactor by reversing the disassembly proce-
dure. Use new C-rings to secure the toggle-link pin.
7. Connect the solenoid coil leads to the lower terminals.
8. Connect the fuse leads to the upper terminals.
NOTE: Be sure coil and fuse leads are positioned for maximum
clearance to other grounded parts
Closing Solenoid
The closing solenoid coil is connected phase-to-phase and is
rated to operate at full system voltage. It is protected with two
fuses, one on either side. A data plate attached to the recloser
head between source side bushings 3 and 5 provides the coil
connection information. If the solenoid coil must be replaced,
due to damage or change in operating voltage, refer to Figure
13 and proceed as follows:
1. Disconnect the two coil leads from the closing solenoid con-
tactor.
NOTE: Reattach the lockwashers and nut to the contactor terminal
immediately after disconnecting the coil lead to prevent loss of parts
of the moving contact arm assembly which is attached to the sup-
port plate with the same hardware.
2. Remove the four capscrews and lockwashers which attach
the base plate to the bottom of the solenoid frame posts and
lower the coil and base plate.
3. Remove the coil from the base plate and discard the coil gas-
ket.
4. Using a new coil gasket, install the new closing coil on the
base plate.
NOTE: A new coil gasket is included in the closing coil
replacement kit.

6. The closing coil replacement kit includes two new coil fuses
which should be installed with the new coil. See Closing
Solenoid Fuses, following, for fuse replacement procedure.
7. The closing coil replacement kit also includes a new voltage
date plate. Replace the plate on the sleet hood of the reclos-
er head if the operating voltage of the recloser is being
changed.
Closing Solenoid Fuses
New fuses are provided with the closing solenoid coil replace-
ment kit and should be installed with the replacement coil.
Fuses can also be ordered separately for individual replace-
ment if damaged. A label, attached to the closing coil, specifies
the catalog number, and color band coding of the proper fuse
required to protect the coil. This information is also listed in
Table 1. To replace a closing solenoid fuse:
1. Disconnect the long fuse lead at the closing solenoid contac-
tor.
2. Disconnect the lead wire from the terminal at the other end of
the fuse.
3. Loosen the mounting strap and slide out the fuse.
4. Install the new fuse and reconnect the fuse leads.
NOTE: Be sure the long fuse lead clears any grounded parts and
insulating supports by at least 1/2-inch.

REPLACEMENT INSTRUCTIONS FOR
CIRCUIT COMPONENTS
All circuit components associated with the recloser frame,
head casting and operating mechanism except the trip
solenoid, rotary solenoid, microswitch 1 and mercury switch
2 can be replaced without detaching the recloser mecha-
nism from the head casting. Instructions for replacing bush-
ing CT’s, mercury switch 3, and the 0.2-MFD capacitor are
given first. A 100-watt soldering iron will meet all require-
ments for repair work. When resoldering lead connections,
use only resin core solder. M-E will assume no responsibili-
ty for components having leads connected by means of acid
core solder.
0.2-MFD Capacitor
The 0.2-MFD capacitor is used on units supplied with the
CT-Type battery charger power source. Label lead connec-
tions to the capacitor and proceed as
follows:
1. Heat solder joints to disconnect leads.
2. Remove screws and bracket that secure capacitor to
recloser frame.
3. Replace by reversing above procedure. Be sure to recon-
nect leads to proper capacitor terminals.
Battery Charging Current Transformer
The battery charging current transformer is used on units
supplied with the CT-Type battery charger power supply.
Label lead connections to the current transformer and shunt
ing resistor. Then proceed as follows:
1. With diagonal cutters, clip the leads close to the current
transformer.
2. Disconnect the flexible bushing lead.
3. Remove the two screws that secure the current trans-
former to the head casting. Bushing CT is now free to be
removed.
4. Replace current transformer by reversing the above pro-
cedure. Be sure to use spacers between the transformer
mounting supports. Replacement transformers are
equipped with six-inch leads which can be trimmed as
required. When splicing connections, be sure the proper
leads are connected before soldering. Be sure to wrap
all splices with electrical tape and observe soldering pre-
cautions recommended above.
Sensing Bushing-Current Transformers
Replacement of phase A, phase B. and phase C current
transformers is identical. These transformers are installed as
described above under battery-charging transformer instruc-
tions.
Mercury Switch 3
Disconnect leads from terminals A and G and proceed as
follows:
1. Loosen two screws that secure nylon mounting straps to
lever pinned to main reclosing shaft.
2. Slip mercury switch from mounting straps when screws
are loosened sufficiently.
3. Be sure to replace mercury switch so that lead wires are
furthest from the rotary solenoid. If the end without lead
wires is not nearest the rotary solenoid, improper opera-
tion of the recloser mechanism will result.
Remove Head Casting for
Removing Components
To replace the following components—trip solenoid,
microswitch 1, mercury switch 2 and rotary solenoid—the
recloser mechanism must be removed from the head cast-
ing, as described on page 10.
Mercury Switch 2
Refer to Figure 14 and install new switch as follows:
1. Disconnect the leads of the mercury switch from the terminal
strip terminals F and G.
2. Remove the four nylon mount) ng straps that secure the sleev-
ing to the recloser frame.
3. Remove the faulty switch from its mounting straps. With an off-
set screwdriver, loosen the screws that secure the nylon straps
to manual-lockout shaft lever to allow removal of switch 2.
4. Pull the leads through the protective sleeving. Thread the leads
of the new mercury switch through the sleeving. Thread both
leads at the same time. Leads can be secured to a long wire
which can draw the mercury switch leads through the sleeving.
NOTE: Switch leads need only be connected between the proper ter-
minals for correct operation. Reversing leads between switch terminals
has no effect on recloser operation.
5. Pass sleeving through mounting straps and tighten to secure
sleeving. Connect switch leads to proper terminals. Position
switch as shown in Figure 14 and secure mounting straps to
lever. If switch is positioned opposite to that illustrated in Figure
14, the recloser will operate improperly.
Microswitch 1
Refer to Figure 15 and proceed as follows:
1. Disconnect the two white leads from the top of the microswitch.
2. Remove two round-head machine screws to release
microswitch from mounting bracket. A hexnut and washer will
be released from the threaded end of the screw.
3. Attach new microswitch to mounting bracket. Adjust micro-
switch so that roller lever stop just touches base of switch when
roller rides on cam. When roller is off cam, it should just clear
flat of cam as shown in Figure 15. Tighten machine screws.
4. Reconnect leads to two terminals nearest rotary solenoid as
shown.
Rotary Solenoid
Refer to Figures 15 and 16 proceed as follows to replace the
rotary solenoid:
1. Drive out the roll pin that secures the spring lever to the rotary-
solenoid shaft. Detach retarding spring from cotter pin.

sure solenoid leads are connected to correct terminals.
Trip Solenoid
The trip solenoid, Figure 17, is replaced as follows:
1. Disconnect leads from terminals A and B of the terminal
block.
2. Loosen the hexnut that secures the nylon mounting strap to
allow lead sleeving to slip through freely.
3. Remove two hexnuts that secure the trip solenoid to the
mounting bracket. Detach trip solenoid from bracket. Two
lockwashers will be released.
4. Install new solenoid by reversing above procedure. Pass
leads through nylon mounting strap and grommet in mecha-
nism frame. Connect leads to terminals A and B of the termi-
nal strip in any order. The trip solenoid is not polarity sensi-
tive.
Removing Mechanism from Head
To gain access to components located in or on the main frame,
the following procedure may be used to remove the mechanism
from the head.
NOTE: These procedures will be simplified if the untanked head and
mechanism assembly can be inverted (bushings down). The unit can be
supported on its bushings.
1. Disconnect all six bushing leads from the rods at the ends of
the bushings.
2. Disconnect the lockout lever and contact position indicator
shafts by disengaging the spring loaded couplers and locking
them in the disengaged position, Figure 18.

Reinstalling Mechanism into Head
To reinstall the recloser mechanism assembly into the head,
the following procedure may be used.
1. Install the couplers on the lockout lever and contact posi-
tion indicator shafts of the mechanism and lock them in
the disengaged position.
2. Carefully lower the mechanism assembly onto the six pipe
spacers which have been positioned over the attaching
holes in the casting (Figure 23).
3. Install the six attaching socket head bolts and tighten even-
ly to avoid any binding of the mechanism.
NOTE: Replace the hex head bolts in tne bottom of the closing
solenoid frame if eye-bolts were used for handling the recloser
mechanism.
4. Re-engage the lockout lever and contact position indicator
shaft by releasing the shaft couplers.
5. Reconnect the operating lever of the auxiIiary switch (if
used ) to the mechanism and secure with the washer and
E-ring (Figure 19).
6. Attach the 0.2 mfd bathtub capacitor (if present) to the
mechanism frame (Figure 20).
7. Reconnect the leads to the respective terminals on the ter-
minal block, and reattach the nylon strap to the frame to
secure the lead bundle (Figure 21).
8. Reconnect the bushing leads to their respective bushings.
Operational Checks
An internal connection diagram of the recloser circuits is
shown in Figure 24. The operating sequence for the various
circuit components is diagrammed in Figure 25. These com-
ponents should provide trouble-free operation with little or no
maintenance. However, if the recloser does not operate prop-
erly, the following checks can be made to trouble-shoot the
recloser circuits.
NOTE: Procedures for checking, testing and troubleshooting the
electronic control are provided in a separate manual (S28O-75-1).
The recloser need not be untanked to perform these checks.
CONTROL CABLE
Using an ohmmeter, check the continuity between like pins and
pin sockets of the connector plugs on either end of the elec-
tronic control cable and for discontinuity between unlike pins
and pin sockets to determine the condition of the control cable.
NOTE: Pins or pin sockets N and P on either plug are not connected.
Repair or replace the control cable if defective.
CIRCUIT COMPONENTS
All measurements are made at the pin sockets of the control
cable receptacle on the recloser head. A reading within + 15
percent of the specified value indicates components are opera
tional. Any component failing to meet the specified checks
should be replaced. Figure 26 identifies the various circuit
components.
NOTE: If the electronic control battery is used to supply the 25 vdc
power, connect as directed for only as long as necessary to perform
the specified action to prevent excessive battery drain.
Trip-Solenoid
1. Connect an ohmmeter between pin sockets A and B.
•The meter should read approximately 9.5 ohms.
2. Lift up the yellow manual operating handle under the sleet
hood and manually close the recloser with the T-handle
closing tool as described on page 5.
3. Momentarily apply 25 vdc to pin sockets A (+) and B (-). .
The recloser should trip.
Rotary Solenoid and Closing Solenoid Contactor
1. Connect an ohmmeter between pin sockets E and F. The
meter should read approximately 19 ohms.
2. With the yellow manual operating handle in the up position
and the recloser contacts open, momentariIy apply 25 vdc to
pin sockets F (+) and E (-).
•The rotary solenoid should operate producing an easily
distinguishable sound. Repeat two or three times.
3. Connect the ohmmeter across source side B and C phase
bushings, or from source side C bushing to recloser ground
(depending upon the recloser coil connection) and again
energize the rotary solenoid.
•The meter should indicate closing coil continuity (read the
effective dc resistance of the closing coil) confirming that
the closing solenoid contactor is closed.
4. With the rotary solenoid still energized, manually close the
recloser with the closing tool.
•The ohmmeter should indicate loss of continuity indicating
that the closing solenoid contactor has opened.
Switches (SW1, SW2, SW3)
Table 2 shows switch for manual operating lever/recloser con-
tact combinations. An ohmmeter connected across the desig-
nated pin sockets of the control cable receptacle will indicate
zero for a closed contact and infinity for an open contact.

Continuity Check
1. Connect an ohmmeter, in turn, to pin sockets K and N. K and
H. and K and J to check the continuity of the three current
sensing transformers.
•The meter should read approximately 7 ohms, the d.c.
resistance of each winding.
2. Connect the ohmmeter to pin sockets K and L to check the
continuity of the battery charger CT winding, if used.
•The meter should read approximately 1000 ohms. A zero
ohms reading indicates the 0.2 mfd capacitor may be short
circuited. Readings deviating more than + 20% from 1000
ohms indicates a damaged resistor or transformer winding.
Ratio Test for Sensing CT's
1. Connect all three phases of the recloser in series as shown in
Figure 27 and close the recloser contacts with the manual
closing tool.
2. Connect a 100 ampere a-c test current to test points 1 and 2.
3. Energize the 100 ampere test source.
4. Using a 0-500 millimeter check the current output across
socket pins K-G, K-H, and K-J (Figure 27A).
•The output of each CT should measure 100 ma + 10%.
NOTE: Be sure to allow for the tolerances of meter being used.
The resistance of certain type of meters is not negligible. Use as
high a scale (lower resistance) as is accurately readable.
5. A 100 ma reading verifies the 1000:1 ratio of the sensing CT’s.
If the 100 ma is not attained the CT winding is probably faulty.
6. De-energize the test source.
Polarity Test for Sensing CT's
1. With the phases still connected in series from the previous
test, connect the secondaries of the CT’s in parallel by con-
necting pin socket G to H to J and measure the output
between pin sockets K and J as shown in Figure 27B.
2. Energize the 100 ampere a-c test source.
A. All three transformers should have the same polarity; the
output should measure 300 ma.
B. If one transformer has its polarity opposite of the remain-
ing two the output will measure 100 ma.
3. De-energize the test source and remove the jumper wire from
the receptacle.
Output Test of Battery Charging CT, if Used
1. With the phases still connected in series, energize 100
ampere a-c source.
2. Measure the output between pin socket K and L of the control
cable receptacle.
•Output should measure 40-60 ma.
