Simulation 2-Channel Partial Discharge Detector

Product Positioning

MOEORW-WPD20 Multi-channel Digital Partial Discharge Detector is a high-precision, anti-interference, efficient intelligent tester fully compliant with IEC 60270, GB/T 7354 and DL/T 417 standards. It provides safe, accurate and efficient partial discharge detection and fault diagnosis for various high‑voltage equipment.

Three Core Customer Pain Points Solved

1. Severe on-site interference leading to inaccurate measurement

Adopts triple anti-interference and analog‑digital hybrid filtering to stably detect weak PD signals even in strong electromagnetic environments.

2. Low efficiency of single‑channel testing

Independent dual‑channel synchronous sampling and simultaneous testing double working efficiency.

3. Complicated data sorting and non‑standard reports

Automatically stores waveforms and generates standard PDF test reports with one click, meeting acceptance and traceability requirements.

Six Core Advantages
