HVA90 Insulation Tester

  • The HVA90 insulation tester by b2 electronics 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 HVA90 may be expanded with optional devices to a full cable diagnostics system.

  • The HVA system may then be used for tan delta measurement
DESCRIPTION

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.

  • Sinusoidal: 0 – 90 kV peak, 0 – 64 kV eff
  • DC: ± 0 – 90 kV
  • Squarewave: 90 kV


The highvoltage insulation tester HVA90 offers various operating modes.
Cable testing, cable sheath / jacket testing, sheath fault location, cable fault conditioning (burning), vacuum bottle test.
