The VLF-200CMF provides a 200kVac peak output voltage, suitable for performing VLF hipot tests on 138kV cable and as a voltage source for Tan Delta and Partial Discharge testing on 230kV cable. The controls offer all the features of our other VLF models along with VLF Cable Burning. Trailer mount optional.
