2．2Main performance characteristics

　1）High sensitivity: The detection sensitivity for metal particles and floating potential discharge can reach5PCCan accurately detect partial discharges emitted by corona and creepage discharge;

2）Good stability: High quality sensors, external noise sensors, and specific filters are selected, advanced detection technology is adopted, and software processing technology is used to enhance anti-interference ability and effectively improve the stability of the instrument;

3）Accurate judgment: This instrument continuously samples, and only when the detected partial discharge signal meets the set "threshold", "environmental noise", and "alarm density", it is judged as abnormal, which improves the accuracy of judgment;

4）The instrument has dual channel monitoring and simple function settings. When abnormal partial discharge signals are detected, it can automatically sound an alarm;

5）Capable of live detection: external sensor, no need to disassembleGISAny component that does not affect the operation of the equipment;

6）Portable design of the instrument: easy to operate, improves work efficiency;

7）Temperature:-5～+45℃, humidity:10～95%RHAltitude ≤4000M.
