CABLE AND JOINT PARTIAL DISCHARGE MONITORING PRODUCTS

The cable partial discharge monitoring terminal captures partial discharge signals generated by insulation degradation using a high-frequency pulse current sensor to assess the condition of the insulation. It is primarily deployed on grounding shield wires of transformers, switchgear cable joints, tap changers, and similar equipment. The cable joint partial discharge monitoring terminal is designed to monitor the magnitude of partial discharge signals at cable intermediate joints. The device features an integrated design, incorporating built-in units for partial discharge signal acquisition, temperature measurement, and water‑infiltration detection, and is powered by an internal battery with wireless communication capabilities. This configuration supports distributed deployment at cable joints, minimizing the need for extensive on-site cabling.

TRANSFORMER PARTIAL DISCHARGE MONITORING PRODUCTS

Partial discharge monitoring for transformers is primarily used in dry-type transformers and pole-mounted transformers rated 10 kV and above. It measures the magnitude of partial discharge signals and provides comprehensive insulation‑condition monitoring through ultrasonic, ground‑electromagnetic wave, ultra‑high frequency, pulse current, and temperature sensors. The monitoring host can acquire and analyze data from each sensor in real time and transmit it to the central system server.
