Abstract

This paper deals with the application of a partial discharge (PD) test on low-voltage electrical and electronic devices, which is recently being accepted as a non-destructive and a effective dielectric test method. A comparative analysis combined with the Withstand Voltage Test (WVT) specified in IEC standards was carried out on low-voltage insulation transformers. The results showed that the WVT causes insulation degradation of the specimen during the test by applying high voltage. However, the PD test can be performed in ranges from 30 % to 50 % of the test voltage specified in the WVT. Therefore, the PD test is successfully applicable for a non-destructive test method on low-voltage electrical and electronic devices as a replacement of the WVT.
