Section C: Operation of the AutoLink
C.1. General
The AutoLink Electronic Sectionalizer is a protection device that operates at a permanent fault in the distribution line. It must be
used together with an upstream recloserorcircuit breaker with reclosure capability. Please take note that the AutoLinkis not a fuse tripping
device, therefore it cannot be used as a protection device by itself.
The main function of the AutoLink is to discriminate between permanent and transient faults in the distribution line, making it
possible for the upstreamrecloser or substationbreaker to clear transient faults without permanent interruptionto the customers.
The AutoLinkis not a fuse tripping device, it willoperate to isolate a permanent fault on no load condition. The AutoLink fits into
a standard fuse cutout and it directly replaces an existing fuse base. When it operates the AutoLink drops open like a fuse.
The AutoLink Electronic Sectionalizer is designed ONLY to protect electrical
equipment and NOT for saving people from accidents or electrocution when
contacting energized circuits.
C.2. Operating Under Fault Conditions
C.2.1. Operating Under Temporary Fault Conditions
In distribution overhead lines 80-90% of the faults are temporary, and are cleared by an upstream recloser or breaker.
Figure 1.
The AutoLink is in monitor mode under normal load conditions. When a fault is present the AutoLink senses a current above a
programmed pickup threshold (Ia AutoLink) and becomes active. It waits an openingof the upstreamrecloser or breaker.At the occurrence
ofzero current, the sectionalizer registers the first count. If the upstream recloser or breaker closesand no further fault is detected (temporary
fault condition) within the memoryresetting time, the AutoLink will time out, reset its counter and return to the monitor mode.

1YSA160003-EN - Rev. 5 6 / 19
Figure 2.
C.2.2. Operating Under Permanent Fault Conditions
Theremaining10-20%offaultsindistributionoverheadlinesareconsideredpermanent.Duringthesefaults,thecontinuouscycling
of the recloser does not clear the fault. .The AutoLink will pickup, measure zero current and count, reaching its trip count setting.
The AutoLink will trip on the last open cycle of the recloser, isolating the permanent fault in its branch and allowing the recloser
to close prior to going to lockoutand maintain power to the unaffected branches.
Figure 3.
The times shown in Diagrams B and C as T1 correspond to the time the recloser takes to reconnect the circuit. This “dead time” is
usuallyadjustable up to 3 minutes. The AutoLink can operate while keeping the count performed with the current at zero for up to
3.5 minutes, above anypossible dead line value configured inthe recloser.
Due to the latest technological improvementsrecentlyintroduced toreclosers, the time indicated as T2 is the time the recloser takes
to open after the fault is detected. The AutoLink, by means of the spectral analysis in the second harmonic, only needs one cycle
to identify a current as a fault current, isolating itfromsymmetric and asymmetric inrush currents. This feature adds an outstanding
technical advantage to the AutoLink.
C.3. Minimum Time Required for Power up the AutoLink
The AutoLink isa self-powered device. The following graphs displays the minimumtime required for the device to be powered at
different currents to enable the operation. The AutoLink can harvest the required energy fromthe precharge current and also from the fault
current as far asit fulfills the time-current requirement for fully charge its main energy storage device. The minimumnominal current of
the AutoLink to be fullycharged is 5A.

1YSA160003-EN - Rev. 5 7 / 19
Figure 4.
C.4. Minimum Autoreclosing Operating Time required for AutoLink operation
The AutoLink requires a line current greater than 5 A in order to be fully charged during at least 15 seconds. After the condition of
the device is fullycharged the line current canvary as lowas3A and it will continue to be operative.
The recloser should set its reclaim time to 15 seconds in order to prevent an auto-reclosing sequence before the AutoLink is fully
charged. If a fault happens before that timer, the recloser goes directly to lockout preventing the recloser cycle operation.
The AutoLink is able to detect a fault on the line witha period assmall as one cycle. So the recloser can beset to start the tripping
command as longasit enables to flow through the sectionalizer one sinusoidalcycleinorder to correctly measure the fault usingits detection
algorithm.
The minimum opening time that the recloser is set to maintain the line deenergized after a fault during a reclosing cycle must be
set higher than 0,5 seconds in order to permit the AutoLink to perform the mechanical trip and safely isolate its connected faulty load and
isolate the fault from the other branches connected to the recloser.

1YSA160003-EN - Rev. 5 11 / 19
Table 1 and 2.
D.4.3.4. Closing of the Unit
Once the calibration current and counts are set, cover the dip-switch with silicongrease (See Figure 3), supplied with AutoLink.
Figure 9.
Check the condition of the O-Ring (See Figure 2-E) and applysilicon grease (See Figure 4-F) both inside the cap and over the dip-
switches.

1YSA160003-EN - Rev. 5 12 / 19

Place the cap, holding the tube with the hand, and tighten it using a 34 mm fork spanner (torque between 8 and 10 Nm) without
damaging the O-Ring (See Figure 5).
Figure 11.
D.4.3.5. AutoLink Repositioning
Push the interlocking bolt (See Figure 6) until blocked (itwill rotate freely). Do not strike the bolt, nor use anytype of tool to reset.

1YSA160003-EN - Rev. 5 13 / 19

D.4.3.8. Mounting the AutoLinks in the three phase body
For each AutoLink place the hookstick in the tube’s lower contact eyelet and mount in the isolating support body.
Figure 17.
Withdraw the pole and place it in the tube’s superior eyelet (See Figure 10). Push it until it remains in closing position.
Figure 18.
REMEMBER! It isnot recommended to close the AutoLink under load.
The line must be measured before to avoid closing under fault for safety reasons.

1YSA160003-EN - Rev. 5 17 / 19
D.5. Commissioning
D.5.1. General procedures
When commissioning, all operations must be carried out by suitable qualified
customer personnel with in-depth knowledge of the apparatus and the installation
itself.
Itisnot recommended to open AutoLink under charge using a common hookstick, as
it could cause an arc that might damage the personnel or the equipment. The
AutoLink has horns to be used with a load break tool.

1YSA160003-EN - Rev. 5 18 / 19
Section E: Maintenance
Test the correct operation of each electronic sectionalizer on a regular basis, preferably while maintenance on upstreamrecloser is
made:
- Check the closing system.
- Check that the interlocking bolt turns freely. The tensioning device support should move easily and the spring should be
sufficientlytightened so that the support may reset when the system opens following the operation ofthe sectionalizer.
- Check that the mobile lever and the lower support ofthe AutoLink move easily at the joint. Clean and lubricate the joint surfaces
of both pieces.
- Keep contact zones clean and place a thin filmof conductive grease onthose zones.
- Keep the tripping pin clean.
- Check the upper contact cap iscorrectly fastened and both the o-ring and the silicon grease are present.
Test should be carried out on a laboratory with the appropriate equipment to simulate service conditions. For this operationit is
recommended to contact ABB to request the testing procedure.
