SETTINGUPTHEEQUIPMENT
The setup of thisequipment hasbeen minimized by careful considerationof the operator during
design. The VLF-34E single-piece construction and light weight lends itself to convenient
portabilityforACtestingin the field.
Select a location for the unit that will allow easy viewing of the control panel at a safe
distancefromthetestobject (within 20ft.)on a levelarea.
Note: The mains outlet that is utilized to power this equipment must be within 3 meters of
the device, and shall be easily accessible and easily disconnected.
1. Be sure that main power switch lower left side of case is off.
2. Secure a ground test lead to the ground stud on the right side of
the case
–CAUTION –
No switches or Disconnect devices in the earth conductor.
Disconnection ofthe protective earth conductor, will impair the
protection provided by the system
3. Wire the input power cord to a grounding-type plug rated for a
minimum of 250V, 10A and compatible to the local power
receptacles.
4. Connect the input line cord (maximum length 3 meters)to mains
outlet.
5. Connect the safety ground stick to a solid earth ground.
6. Insert the coaxial output cable into the High voltage output dry-well
on the right side of the case and stretch out for later connection to
the test cable or load.

7. Insert the EXT INTLK plug into the socket on the left side panel.The
plug may also be wired to a normally open contact of a safety switch for added
protection.
-IMPORTANT NOTE -
DO NOT BLOCK THE COOLING VENTILATION OPENINGS
The setup of the VLF AC Test Set does not address the need for proper safety
grounding of the load (test sample or cable). The grounding requirements vary for
different types of tests. Please consult the local electrical codes where applicable or
reference the guidelines for grounding found under OPERATING THE EQUIPMENT.

OPERATOR MANUAL
OperatingtheEquipment
This section provides step-by-step instruction on various test methods. Many facilities
have their own in-house test procedures, and this manual is not to supercede these.
The purpose of this section is to explain the capabilities of this test set in real-world
applications.Only trained personnel should attempt to operate this equipment.
Dangerous voltages and currents are produced during the testing of cables, only
trained individuals should operate this type of equipment and access to the test
area must be restricted during testing toavoid endangering others.
OPERATING THISEQUIPMENT IN A MANNER NOTSPECIFIED BYTHE
MANUFACTURER MAY IMPAIR THE PROTECTION PROVIDED BY THIS
EQUIPMENT
When testing cables, either single or three phase, there are certain extra steps that must be
observedtoensuresafe operation.
ACTesting of High Voltage Cables
1. Ensure that all the steps listed in Setting Up the Equipment have been
accomplished.Takespecialnotetogroundthetestsettoasolidearthground.
Caution!!
Before making any cable connections, ensure that the cable
being tested has been properly identified, de-energized,
and grounded!
2. Make sure that all insulators, stress cones, and pot heads are clean and free of
moisture.Thiswillpreventflashoverandminimizeleakage.
Note: Be aware that any lightning arrestor or transient suppressing device must
be disconnected if the clamping voltage is below the test voltage being
performed. Failure to clear these devices from the cable may result in a false
failure indication of the test cable.
3. Isolate the far end of the conductors under test forthe test voltage; that may mean
separating some of the conductors in a multi-conductor cable from each other and
theirshields.

OPERATOR MANUAL
The shields of all cables must be securely tied to
ground at the nearest end of the cable.
4. Any conductors or wires in the cable or the vicinity not being tested must be
groundedtoavoidabuildupofchargeandpossibleshockhazard.
5. Voltagemustbe applied accordingto specifications from the cable manufactureror
anyotherapplicable test standards
6. Prior to connecting anything to the test sample, be sure the test sample is
identified,de-energizedandgroundeduntilreadytotest.
7. Connect the input power cable to a grounded, 50/60 Hz source as noted in
SETTING UP THEEQUIPMENT. Ageneratorisanacceptablepowersource.
8. Connecttheoutput lead to the testsample. Besure that there is enough clearance
to grounded objects for the expected test voltage. The minimum clearance in air is
10kVac/inch.
9. Turn ontheMAIN POWER switch nearinputpowerreceptacle.
***CAUTION***
POTENTIALLY LETHAL
VOLTAGES MAY BE PRESENT
STORED ENERGY LEVELS IN THE CABLE GREATLY
INCREASE THE RISK OF FATAL INJURY IF CONTACT
IS MADE WITH THE LOAD WHILE AT ANY VOLTAGE.
10. Clear the test area of unauthorized personnel and use safety barricades to
warn others of potential danger during the highvoltage test.
