HVA 54-5

VLF High Voltage Test Set

A striking output load of 5 µF @ 38 kV @ 0.1 Hz at only 175 kg of weight, illustrates the capability of this instrument. At 0,1 Hz a cable length of approx. 20 km can be tested, and at lower frequencies, testing of cables of up to 60 km in length are possible. This fully symmetrical output waveform is also the precondition for Cable Diagnostics.
