HVA90

The HVA90 is the most advanced HV test system available, it is also the lightest, most compact instrument of its type on the market. The HVA90 has the highest power to weight ratio of any comparable unit available.

There is no need to carry two pieces of equipment around and then interconnect them!

Apart from the variable frequency VLF output, the operator can also select dual polarity DC and cable jacket or sheath testing output modes.

The HVA90 is capable of testing 1μF (Approx. 3300m / 11,000 ft of cable) at 0.1Hz and 64kV rms. The frequency of the output can also be reduced allowing even larger capacitance loads to be tested. At 0.01Hz, approx. 33,000m / 100,000ft of cable can be tested.
