Product Characteristics
1, high sensitivity. The detection sensitivity of metal particles and floating potential body discharge can reach 5PC, and the partial discharge emitted by corona and creepage can be accurately detected.
2, good stability. The selection of high-quality sensors, external noise sensors and special filters, the use of advanced detection technology, with software processing technology, so that the anti-interference is strong, effectively improve the stability of the instrument.
3, accurate judgment. The device continuously samples in real time, and only when the detected partial discharge signal meets the set "threshold", "density" and "credibility" at the same time, it is judged as abnormal, and the judgment accuracy is improved.
4, perfect data analysis function. The device has a perfect record to analyze the phenomenon of office release during GIS operation, determine the occurrence and development law of office release, and provide a basis for maintenance.
5, local and remote alarm. The device is equipped with local sound and light alarm function and remote software interface alarm function.
6, the device adopts RS485 communication, communication distance is long and reliable.
