PD3000 Partial Discharge Monitor provides continuous monitors of partial discharge (PD) in equipment such as transformers, cables in switchgear and rotating machines, etc. You can call this monitor partial discharge monitoring switchgear too.
It analyzes RF emissions in the HF, VHF, and lower UHF ranges by sensors outside the cabinet. HMI unit provides site display of TEV amplitude and ultrasonic amplitude. DO port can drive local alarms and multi-level alarm notice site engineer. The partial discharge monitor also can communicate data and notifications across standard RS485 Modbus interface to networked supervisory systems.
