OPERATOR MANUAL
Operating the Equipment
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 to avoid endangering others.
OPERATING THIS EQUIPMENT IN A MANNER NOT SPECIFIED BY THE
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
observed to ensure safe operation.
AC Testing of High Voltage Cables
1. Ensure that all the steps listed in Setting Up the Equipment have been
accomplished. Take special note to ground the test set to a solid earth ground.
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. This will prevent flashover and minimize leakage.
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 for the test voltage; that may mean
separating some of the conductors in a multi-conductor cable from each other and
their shields.
