System Performs 138-kV Cable Hipot Tests

High Voltage Inc.'s VLF-200CMF provides a 200 kVAC peak output voltage, suitable for performing VLF hipot tests on 138-kV cable. It is also suited as a voltage source for tan delta and for partial discharge testing on 230-kV cable.

The controls offer all the features of the company's other VLF models along with VLF cable burning, used to reduce fault arc over voltages to permit the use of conventional thumpers to be used for fault locating. A trailer mount is optional.
