The HVA90 insulation tester is a portable 0.1 Hz VLF cable test system for the testing of medium voltage cables. With its weight of 127 kg the hipot tester provides an excellent power-to-weight-ratio.
The powerful output is capable of driving capacitive loads of up to 10 μF. At maximum output voltage cables with a length of up to 33 km can be tested. The HVA90 offers various operating modes. Cable testing, cable sheath / jacket testing, sheath fault location, cable fault conditioning, vacuum bottle test.
