High-Frequency Partial Discharge Live Testing for Cables
Non-intrusive live testing with high-frequency signal capture for accurate partial discharge detection, fast troubleshooting, and efficient protection of power equipment safety.
When partial discharge occurs in power equipment, pulse current is usually generated on the grounding lead or other ground-potential connection lines. By using a high-frequency current sensor to detect the high-frequency pulse current signal flowing through the grounding lead or other ground-potential connection lines, live partial discharge testing of power equipment can be achieved.
