Detailed Overview

The Rugged Monitoring PD201 is a compact design, designed for reliability Partial Discharge (PD) Monitoring Module for Transformers, Switchgears, Power Cables and Rotating Machines. The PD201 PD Monitor combines reliability and user friendly configuration software. It has two variants, 04 channel and 08 channels, that can connect to 4 and 8 PD sensors respectively. The system can be integrated with wide range of PD sensors such as, HFCT, TEV, Bushing Adaptors, Capacitive Couplers, Acoustic, and Ultrasonic PD sensors. 

The PD201 connects to the HF PD sensors installed at the MV/HV assets. It measures the High Frequency (HF) signals emitted by the PD Faults in HV/MV assets. The HF signals are then analyzed for PD activity and Module categorizes pulses as 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 int the module and also 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.
