HVA54-5 VLF High Voltage Test Set

A striking output load of 5 µF @ 38 kV @ 0.1 Hz at only 175 kg of weight, illustrates the capability of this instrument. At 0,1 Hz a cable length of approx. 20 km can be tested, and at lower frequencies, testing of cables of up to 60 km in length are possible.


This fully symmetrical output waveform is also the precondition for Cable Diagnostics. All HVA test sets are upgradeable to a Cable Diagnostic System, such as Tan Delta (TD) and Partial Discharge.

Output voltages:

  • Sinusoidal: 0 – 54 kV peak, 0 – 38 kV peak
  • DC: ± 0 - 54 kV
  • Squarewave: 54 kV

The HVA54-5 VLF hipot tester 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 HVA54-5 VLF hipot tester the outstanding cable test system of its class:

  • Predefined standard-compliant cable test sequences
  • Symmetrical sine wave at high voltage
  • RMS measurement of output voltage and current
  • Measurement of capacitive and resistive load
  • Automatic load dependent frequency selection (0.01 Hz – 0.1 Hz)
  • Display of current test time
  • Integrated real-time scope function
  • Self-explanatory, multilingual software
  • Automatic measurement reporting
  • Report storage via RS232 or USB
  • PC software (b2Control Center) for data analysis and storage
  • Flashover detection
  • Flashover voltage measurement
  • Time optimized burning mode
  • No regular maintenance required


The fully comprehensive safety features guarantee protection of operator and test instrument.

  • Short circuit protected output
  • 12 kV feedback protection
  • Signal lamps for active / inactive high voltage
  • Status display of safety functions
  • Dual Discharge Device DDD®, elektronische und mechanische Entladeeinrichtung (integriert)
  • Main switch with key-lock
  • Emergency-off button on front panel

A SINGLE device for NUMEROUS applications:

  • Cables: XLPE , PE, EPR, PILC, etc.
  • Capacitors
  • Switchgear
  • Transformers
  • Rotating machines (IEEE 433)
  • Isolators
  • Bushings

The HVA54-5 VLF hipot tester may be expanded with optional devices into to a full cable diagnostics system.


The HVA system may then be used for partial discharge and tan delta diagnostics
