The HVA94 cable tester by b2hv is a portable 0.1 Hz VLF cable test system for the testing of medium and high voltage cables.

With its weight of 128 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.

Maximum output voltage cables with a length of up to 50 km can be tested.


  • Sinusoidal: 0 – 94 kV peak, 0 – 66 kV rms
  • DC: ± 0 – 90 kV
  • Square wave: 90 kV

The HVA94 cable tester offers various operating modes:

  • Cable testing
  • Cable sheath / jacket testing
