HVA34 Hipot tester

The HVA34 hipot tester by b2hv is a portable 0.1 Hz VLF cable test system for the testing of medium voltage cables.

 

At only 19,5 kg this ultra light hipot tester is truly quite remarkable and as such is ideal for mobile use.

The powerful output is capable of driving capacitive loads of up to 12 μF.

 

At maximum output voltage cables with a length of up to 8 km can be tested.

 

Possible output voltages:

  • Sinusoidal: 0 – 34 kV peak, 0 – 24 kV eff
  • DC: ± 0 - 34 kV
  • Squarewave: 34 kV

 

The Dual Discharge Device (DDD®) allows electronic and mechanical discharging of devices under test.

The HVA34 hipot tester offers manual and automatic testing and diagnostic sequences and various operating modes such as:

  • VLF cable testing with symmetrical AC-Voltage (load independent across full range)
  • DC with positiv or negative polarity
  • Burn-/ Fault Condition or Fault Trip Mode
  • Jacket / Sheath Testing
  • Sheath Fault location mode
  • vacuum bottle test

 

The following features make the HVA34 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 USB or RS232
  • PC software (b2 ControlCenter) 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 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 HVA34 hipot tester may be expanded with optional devices into to a full cable diagnostics system.

 

The HVA system may then be used for tan delta measurement

or partial discharge measurement
