Partial discharge detection is of great significance to high-voltage cables and to study the characteristics of partial discharges in insulation, especially power cables.

The significance of partial discharge detection for insulation products:
Partial discharge will lead to gradual aging of insulation (so in the industry, we take the measurement of partial discharge as the main means to assess the electrical aging of cross-linked cables), the power (operation) department can use partial discharge as a preventive test for insulation. If the insulation does not have partial discharge under the working voltage or does not exceed a certain amount of partial discharge, the long-term and reliable operation of the cable insulation can be ensured;
Partial discharge test is a non-destructive test. It can be used to assess the quality of products and detect defects inside the cable. Now, the detection of partial discharge has become one of the main technical indicators of the quality of our products in the cable and insulation industry.
