HIGH POWER TESTING

High Power Testing

ITL is only one of a handful of facilities in the southern hemisphere which offers high power testing services, including high voltage, heavy current and high impulse.

From within our separate and isolated control room, we can offer clients a safe, accurate and reliable way to evaluate concepts and prototypes for R & D purposes, or to test finished products which may need to comply with regulations or meet international standards.

As an independent high power testing facility, you can be sure of the absolute integrity of the test data and results from ITL. You will also find us flexible and accommodating, so that we can meet your exact testing needs.

If you require high power testing of semi-conductors, surge protectors, transformers, circuit breakers or electrical boards etc., our robust facilities and highly experienced team can offer you a comprehensive package or tailored, flexible service.

Our facilities

For safety reasons, we have a well established and separate facility in the heart of Christchurch’s industrial estate, readily available for both local and international clients and conveniently close to the airport.

Our engineers have a wealth of testing experience both in New Zealand and on a variety of international standards. We utilise robust test equipment and meters and our data acquisition is controlled via digital and fibre optic links.

For accurate analysis, our high power testing equipment is calibrated with a tolerance of just +/- 1%. We are capable of supplying ac/dc withstand voltages up to 300kV, ac short circuit currents exceeding 40,000 Amps and impulse voltages of up to 600kV.
