Transformer partial discharge online monitoring system (pulse current method)
Monitor the basic partial discharge parameters such as discharge volume, discharge phase, discharge times, and provide relevant statistical parameters according to customer requirements.
The minimum measurable discharge capacity is 500pC; the measurement frequency band is 40k～3MHz; the resolution of the discharge pulse is less than 10µs; the phase resolution is 0.18°.
Display power frequency periodic discharge diagram, two-dimensional (Q-φ, N-φ, N-Q) and three-dimensional (N-Q-φ) discharge spectra.
Using a database, it can record related parameters such as discharge volume and discharge times, and provide multiple functions such as discharge development trend analysis, setting alarms, historical queries, and printing reports.
It can automatically start monitoring at regular intervals to realize the automation of the whole monitoring process; it can also start and close the monitoring system manually in real time.
It can realize functions such as remote communication and data access, and supports network communication protocols such as CAN bus and TCP/IP protocol.
