Product Introduction
MOEORW-WUHF-TEV-AA
This 3‑in‑1 PD sensor integrates UHF, TEV and AA ultrasonic detection to eliminate blind spots caused by single‑sensing solutions.
‑ TEV: Captures transient earth voltage from cabinet surfaces to spot internal metal discharge defects
‑ AA Ultrasonic: Picks up ultrasonic signals generated by insulation surface degradation
‑ UHF: Receives PD‑radiated electromagnetic waves to filter external site interference
Three channels sample simultaneously for cross‑check analysis, minimizing false and missing alarms. Magnetic mounting requires no drilling or cabinet modification for fast installation inside switchgears and RMUs.

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.
