Cable High-Frequency Partial Discharge Live Detection (Distribution Network)

Features or Overview

1. Live detection: tests can be performed while the cable is in normal operation, without interrupting power supply; 2. High-frequency accuracy: high-frequency sensing captures partial discharge signals precisely to identify insulation risks effectively; 3. Easy operation: the workflow is simple and adapts to a variety of cable scenarios without complex tuning; 4. Safe and efficient: insulation issues are identified in real time, risks are warned early, and long-term stable operation is supported.

When partial discharge occurs in electrical equipment, pulse current is usually generated on the grounding lead or other grounded connection. By using a high-frequency current sensor to detect the high-frequency pulse current signal flowing through the grounding lead or other grounded connection, live partial discharge detection of the power equipment can be achieved.
