Data sheet

Overview

VLF output voltages of up to 200 kVpeak allow you to perform voltage withstand tests on assets with network voltages as high as 141 kVrms. Our HVA200 system is far more compact and lightweight than any other withstand testing solution providing this voltage level. The test system can optionally be upgraded with a highly sensitive cable diagnostic module to perform PD and TD diagnostics in addition to the withstand test.The HVA200 is for laboratory use or can be fitted as a mobile test laboratory into a van. The smallest and lightest VLF unit of its class offers VLF (Very Low Frequency) 0.1 Hz standard testing as well as DC output voltage up to 200 kV.

Performance

Outstanding features in terms of size, weight (950 kg) and performance (max. 10 µF).

Duty cycle

Operating time of this test set is not thermally limited; it may operate continuously.

Connectivity

On site, no external PC is needed. All results can be later downloaded via optical fiber or USB for further investigation and easy reporting via software tool.

High power

Sufficient power to charge cables up to 10 µF, allowing to test extra-long cables.

Service and maintenance

With only a small amount of oil used, the HVA200 test set is an almost dry-type test system. This means less maintenance and no hassle during transport. Acceptance or maintenance hipot/proof testing using VLF high voltage sinusoidal AC allows the operator to efficiently detect serious cable insulation defects, before they result in an in-service failure, without affecting those healthy sections of the cable that still have remaining service life.
