Product Introduction
MOEORW-W5086KC is an independent multi-channel on-line monitoring device designed for medium-voltage switchgear. It adopts UHF, TEV and AA sensing technologies to realize synchronous detection of partial discharge signals, supporting POE power supply and non-intrusive installation. Equipped with PRPD/PRPS spectrum analysis and phase correlation algorithm, it accurately identifies insulation defects and reduces false alarms.
