SPD800 portable substation charged PD detection system

SIRUIdeveloped a portable substation monitoring PD charged detection system for detection of insulation defects energized substation equipment. The system Electro acoustic detection method based on the use of high-speed digital storage oscilloscope Bureau recording and analysis equipment put signal, the system can compare the analysis of UHF (UHF), ultrasound (AE) and high-frequency current (HFCT) signals of different bands information to effectively distinguish between real PD signal and external interference signals. UHF system to detect the main substation equipment to support a variety of internal and external UHF sensors, measuring equipment can be treated in the operating state of partial discharge testing and diagnostic analysis and, based on the strength of the signal propagation delay and , precise positioning and judgment defect type, degree of hazard assessment of defects in order to understand and master the operational status of equipment, to avoid major accidents.
Main features:
1, a combination of UHF, ultrasound and high-frequency current detection technology can effectively solve the substation site PD testing interference problems and improve the reliability of the test results;
2, using high-speed digital storage oscilloscope, you can analyze UHF, ultrasound and high-frequency current waveform details and the time domain signal characteristics;
3. Test to UHF patrol the main problems found combined ultrasound and high-frequency current sensing; PD live test speed, high efficiency;
4, the use of Electro acoustic detection technology that can accurately locate the source partial discharge analysis, high positioning accuracy;
5, you can put the phase characteristics of the signal waveform characteristics and according to Bureau to determine the type of the Council;
6, the system can be used for office substation GIS, switchgear, transformers and power cables and other equipment to put live testing.
