Description

With its weight of 127 kg the HVA90 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 lengthof 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.

The following features make the high voltage HVA insulation tester the outstanding cable test system of its class:

  • Predefined standard-compliant cable test sequences
  • Symmetrical sine wave high voltage
  • RMS measurement of output voltage and current
  • Measurement of capacitive and resistive load
  • Automatic and load dependent frequency selection (0.01 Hz – 0.1 Hz)
  • Display of current test time
  • Integrated real-time scope function
