Non-Destructive Testing for Reliable Products

PD measurements with the GTU860 and pulse shaped test voltages offer completely new possibilities for electrical motor testing. Now there is the ability to test the isolation between phases and single turns. This enables new non-destructive tests for more reliable products.

The Detection of Partial Discharges

Partial discharges are detected with an HF current transformer. The advantage is the isolation to the high voltage. The measurement is performed with a method developed by Solfas that works in the UHF range with high sensitivity. The attenuation against interference in the frequency range below 100 MHz is very high, which allows measurements with pulsed voltages such as converter output voltages.
