Product Description

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.

• Rugged, compact design sensor detects TEV and audible ultrasonic.
• Non-intrusive and wall-mounted unit design, magnetic adsorption easy installation.
• Panel mount HMI unit provides automatic PD data acquisition and analysis.
• HMI supports max 96pcs sensor, optional wireless, and wired(RS485) connection.
• Multiple configurable alarms, provide 2*DO NC & NO contact for external alarm trig.
• RS 485 MODBUS-RTU easy integration into existing SCADA systems.
