01
High stability
High-quality sensors are used, the acquisition unit adopts advanced detection technology, and specific filters are used in internal configuration. Combining software processing technology, the system has strong anti-interference performance, and the stability of the instrument is effectively improved.
02
Complete data analysis function
The device has complete records, analyzes partial discharge that occurs during the operation of GIS, has a partial discharge pattern library and identification algorithm, and provides identification of background noise, typical interference and partial discharge type. It can determine the occurrence and development rules of partial discharge, and provide a basis for maintenance.
03
Local and remote alarms
The device is equipped with local sound and light alarm function and remote software interface alarm function. This device supports IEC61850 communication with long and reliable communication distance. The internal/external sensors in the device have the same service life as the main device, while the field IED and other components have a service life of 8-10 years.
04
Accurate judgment
The device samples continuously in real time. When the detected partial discharge signal meets the set "threshold", "density" and "reliability" at the same time, it is considered as abnormal, which improves the accuracy of judgment.
05
High sensitivity
The equivalent height of UHF sensor is >12mm, and the sensitivity of the acquisition unit is better than 7V/m.
