Product Introduction
MOEORW-WUHF-TEV-AA is an innovative multi-channel comprehensive partial discharge detection sensor that integrates the functions of three traditional independent sensors into one, solving the problem of missed detection by single detection technology in complex power sites.
The TEV channel detects transient earth voltage signals on the cabinet surface to identify internal metallic discharge; the AA channel captures ultrasonic signals generated by insulation surface discharge; the UHF channel receives ultra-high frequency electromagnetic signals to effectively eliminate external interference. The three technologies complement each other to accurately distinguish partial discharge from on-site interference signals, avoiding false alarms and missed detections. The sensor adopts a magnetic adsorption design, no drilling required, and can be flexibly deployed in key parts of power equipment.

FAQ
Q1: Do the three detection channels work simultaneously?
A: Yes. The three channels collect signals synchronously, and the backend system performs cross-validation to improve fault judgment accuracy.
Q2: What types of partial discharge can it detect?
A: It can detect metallic contact discharge, insulation surface discharge, air gap discharge and floating potential discharge.
Q3: Can it be installed inside the switchgear?
A: Yes. The compact magnetic design allows installation on the inner surface of metal-clad switchgear without affecting equipment operation.
Q4: Is it suitable for temporary inspection or long-term online monitoring?
A: Both. It can be used as a portable inspection tool or fixed for long-term online monitoring.
