High-voltage switchboards, vacuum switches and busbars are often recommended to be tested at 50 Hz.

We perform testing up to 120 kV and can combine the high voltage test with PD measurement

Detects weaknesses that generate partial discharges at normal operating voltage. Performed on systems without the need for downtime. The equipment can also be temporarily mounted for monitoring over time

High-voltage switchboards, vacuum switches and busbars can be tested with DAC 20-300 Hz.

We perform testing up to 65 kV and can combine the insulation test with partial discharge and TanDelta diagnosis.
