PDG-1000 continuously monitors partial discharge (PD) in equipment such as transformers, cables in switchgear rotating machines, etc.
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, ultrasonic amplitude, DO port can drive local alarms, Multi-level alarm notice site engineer. PDG-1000 also can communicate data and notifications across standard RS485 Modbus interface to networked supervisory systems.
