Detailed Overview

The Rugged Monitoring PD211 is a compact design, designed for reliability Partial Discharge (PD) Monitoring Module for Transformers, Switchgears, GIS and Power Cable Terminations. The PD211 is based on the UHF (Ultra High Frequency) technology for PD signal acquisition and analysis. The PD211 Monitor combines reliability and user-friendly configuration software. It has two variants, 04 channel and 08 channels, that can connect to 4 and 8 UHF-PD sensors respectively. The system can be integrated with any UHF PD sensors that are having response between 100Mhz to 2000MHz.

The PD211 connects to the UHF PD sensors installed at the MV/HV assets. It measures the Ultra High Frequency (UHF) signals emitted by the PD Faults in HV/MV assets. The UHF signals are then analyzed for PD activity and categorization of Internal PD, External PD and Noise Signals. Internal PD signals are captured and stored for further analysis such as PRPD, PD Amplitude, Discharge Rate, and trending. The PD amplitude and discharge rate is sent to the third-party system via Modbus (RTU) protocol using built-in serial (RS-485) port. The PRPD data is stored into the module and sent to third party system via CANBUS protocol using built-in CAN port. There is a dedicated team of experts available for customizing partial discharge monitoring solutions to meet specific customer needs.
