High voltage and heavy current testing laboratory

Industrial Research’s high voltage and heavy current test facility, operated by an independent company, PowerLab Ltd, has testing capabilities ranging from lightning impulse testing on distribution transformers and insulators, to heavy current testing of earth clamps and temperature-rise measurement of busbars. It is capable of supplying voltages up to 700kV, AC withstand voltages up to 300kV, and AC short circuit currents up to 20,000 Amps.

Services offered include:

  • Non-destructive type testing of electrical equipment.
  • Insulation tests for predictive maintenance of electrical plant.
  • Insulation condition monitoring.
  • Impulse voltage and current testing.
  • Short circuit testing.
  • Temperature rise testing.
  • EMC (electromagnetic compatibility) testing.
  • General electrical measurements at high voltage and heavy currents.
  • Partial discharge and tan delta testing (on-site and in laboratory).
  • Investigation of insulation failure and cause identification.
  • Specialist electrical product testing such as electric fence energisers.

The laboratory also offers expert assistance during the design, development and performance assessment of locally developed products.
