MOEORW-5087C Cable HFCT Partial Discharge Online Monitor Send email to us

       The MOEORW‑5087C on‑line partial discharge (PD) monitoring device is engineered for high‑voltage electrical equipment. Supported by HFCT high‑frequency current sensors, it enables long‑term on‑site partial discharge monitoring while target assets remain in service.

        This system consists of a PD acquisition unit and HFCT sensors. The acquisition unit offers three parallel measurement channels to interface with up to three HFCT sensors simultaneously. It samples partial discharge pulse signals, extracts discharge characteristic parameters, and generates PRPD and PRPS patterns. Dual communication interfaces are deployed for data delivery. The Ethernet port transmits pattern datasets, whereas the RS‑485 interface (Modbus protocol) outputs PD characteristic quantities and alarm messages. Upon alarm triggering, pattern data will be locked to preserve anomaly records for post‑event analysis.

       Two power supply variants, 220 V and 24 V, are available. Housed in a metallic DIN‑rail‑mounted enclosure, the unit adopts passive natural cooling for field deployment. Both the main unit and sensors feature a 3 MHz‑30 MHz operating bandwidth alongside a 60 dB dynamic range, with power‑frequency synchronization supported. Capable of stable operation within ‑25 ℃ to +55 ℃, the device evaluates insulation conditions of high‑voltage apparatus in real time and identifies potential insulation defects at an early stage.
