PD201 Rugged Partial DischargeMonitoring Module for OEMs
The Rugged Monitoring PD201 is a compact design, designed for 
reliability Partial Discharge (PD) Monitoring Module for Transformers, 
Switchgears, Power Cables and Rotating Machines.
PD201 combines accuracy and easy to use 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 in the module and sent to third 
party system via CANBUS protocol using built-in CAN port.
