HVA94 cable tester

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.

At maximum output voltage cables with a length of up to 33 km can be tested.

  • Sinusoidal: 0 – 94 kV peak, 0 – 66 kV rms
  • DC: ± 0 - 90 kV
  • Squarewave: 90 kV


The HVA94 cable 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 high voltage HVA94 cable 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
  • Self-explanatory, multilingual software
  • Automatic measurement reporting
  • Report storage via RS232 or USB
  • PC software (b2Control Center) for data analysis and storage
  • Flashover detection and ultra fast switch off
  • Flashover voltage measurement
  • Time optimized burning mode
  • No regular maintenance required

 

The fully comprehensive safety features of the highvoltage cable tester guarantees protection for 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®), two integrated and automatic discharge devices
  • Main switch with key-lock
  • Emergency-off button on front panel


A SINGLE insulation tester for NUMEROUS applications:

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


The HVA94 may be expanded with optional devices to a full cable diagnostics system.

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

or partial discharge measurement.
