On-line monitoring system for ultra-high frequency partial discharge of transformer

System detection frequency band: 300MHz~1500MHz; Minimum monitorable: -75dBm discharge capacity in the laboratory, -70 dBm discharge capacity in the field; The system can measure discharge capacity, discharge phase, discharge times, and discharge pulse resolution is less than 10μs, and can provide relevant statistical parameters according to customer requirements; The system can display power frequency periodic discharge graphs, two-dimensional (Q-φ, N-φ, N-Q) and three-dimensional (N-Q-φ) discharge spectra; Provides many functions such as discharge development trend analysis, alarm setting, historical query and report printing; The system can automatically start monitoring at regular intervals to realize the automation of the entire monitoring process, and it can also start and close the monitoring system manually in real time; The system has built-in four standard discharge mode libraries, which can identify discharge types, evaluate insulation defects caused by different types of discharge trends, and give alarms for abnormal conditions; The system structure complies with the Smart Substation Guidelines Q / GDW 383-2009 "Technical Guidelines for Smart Substations", which is suitable for the intelligent transformation of substations and new intelligent substations. The data server in the system station control layer cabinet has CAC function, built-in I2 data interface and directly communicates with the current state monitoring system of power transmission and transformation equipment of various provincial companies.
