I SWITCHGERA PROTECTION RELAY SCM-PD3000 PARTIAL DISCHARGE MONITOR i Introduction Partial discharge is a kind of pulse discharge, which will produce a series of physical phenomena and chemical changes such as light, sound, electrical and mechanical vibration in the interior and surrounding space of power equipment. When insulation defects appear inside high-voltage electrical equipment, it will be accompanied by the generation of partial discharge signals. SCM-PD3000 partial discharge monitor can be used with UHF sensor, TEV sensor, Ultrasonic sensor and online detection of partial discharge of high voltage equipment such as transformers, high voltage switchgear, and cable joints. Easy to carry, fast measurement, strong anti-interference ability, easy to use on site. • Wall-mounted installation. • Alarm multi-level threshold setting. • Waveform data recording function. • RS 485, Modbus-RTU, SCADA systems. • Sensor detects TEV and audible ultrasonic. • Automatic PD data acquisition and analysis. • 2*DO NC & NO contact for external alarm trig. • Anti-interference performance and high measurement accuracy. • Joint detection of partial discharge signals by transient earth waves. • HMI supports max 96pcs sensor, optional wireless, and wired(RS485) connection.
