HVA120 Insulation tester

The HVA120 insulation tester by b2hv is a powerfull 0.1 Hz VLF cable test system for testing of medium voltage cables.


Output Voltages:

  • Sinusoidal: 0 – 120 kV peak, 0 – 85 kV rms
  • DC: ± 0 - 100 kV
  • Squarewave: 100 kV


The highvoltage insulation tester HVA120 offers various operating modes:

  • Cable testing
  • cable sheath / jacket testing
  • sheath fault location mode
  • 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
  • Absolute 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 (b2 ControlCenter) for data analysis and storage
  • Flashover detection and switch off
  • Flashover voltage measurement
  • Time optimized burning mode
  • No regular maintenance required

 

The fully comprehensive safety features of the highvoltage insulation tester guarantees protection for operator and test instrument.

  • Short circuit protected output
  • 12 kV feedback protection (50 Hz)
  • 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 HVA120 may be expanded with optional devices to a full cable diagnostics system.

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