Product Introduction
MOEORW-WZ-TEV-AA is an intelligent integrated partial discharge sensor optimized for outdoor distribution equipment such as ring main units and box-type substations. It adopts dual detection technology of TEV and AA, which can comprehensively perceive internal insulation discharge signals of the equipment.
The sensor features a full CNC aluminum housing and epoxy resin overall potting process, providing excellent waterproof, dustproof and anti-corrosion performance to adapt to complex outdoor environmental conditions. The innovative daisy-chain power and communication design allows up to 16 sensors to be connected to a single cable, significantly reducing wiring costs. The built-in high-performance microprocessor analyzes and processes the collected signals in real time, directly outputting characteristic values such as discharge peak and pulse count.

FAQ
Q1: What is the difference between this model and WP70?
A: This model is optimized for outdoor environments, with enhanced anti-vibration and anti-corrosion performance, and built-in watchdog circuit for higher reliability.
Q2: Can sensors be replaced without powering down the entire system?
A: Yes. The hot-swappable daisy-chain design allows replacing a single sensor without affecting the operation of other sensors in the chain.
Q3: What data does the sensor output?
A: It outputs real-time discharge peak value, pulse count and signal intensity, which can be directly used for equipment status evaluation.
Q4: Is it compatible with third-party power monitoring systems?
A: Yes. It uses standard Modbus RTU protocol, which can be seamlessly connected to SCADA, EMS and other mainstream power monitoring systems.
