The single piece HVA30 is not only the most advanced high voltage VLF (Very Low Frequency) test system available; it is also the lightest, most compact instrument of its type on the market. HVA30 is also suitable for testing transformers, switchgear, rotating machines and other electrical apparatus.

The HVA60 is not only the most advanced HV test system available, it is also the lightest, most compact instrument of its type on the market. The HVA60 has the highest power to weight ratio of any comparable unit available. The HVA60 is capable of testing 1µF (Approx. 10,000 ft/ 3000m of cable) at 0.1Hz and 60kV peak. The frequency of the output can also be reduced allowing even larger capacitance loads to be tested. At 0.02Hz, approx. 50,000 ft/15,000m of cable can be tested.

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.

The TD30 provides the testing and commissioning engineer with a versatile high voltage tandelta measuring system suitable for testing electrical plant including cables: XLPE, PE, EPR,PILC etc, capacitors, switchgear, transformers, rotating machines, insulators and bushings.

Tan Delta testing enables the cable test engineer to detect insulation defects before the cable fails in service. The TD60 is a versatile tan delta measuring system that is directly connected to the H.V. Diagnostics and HVA Series of VLF Test Systems.

A Partial Discharge is a partial electrical breakdown in the dielectric material which does not bridge the dielectric between the conductor and the concentric neutral. The unit of partial discharge measurement is the Pico Coulomb (pC).

Weight 22kg (48,5lbs). Test Voltage up to 75kV. Internal Battery External 12V Supply. Direct measurement of output voltage. Measurement of silicone oils.
