PRS-7973 Digital Fault Recorder
The PRS-7973 digital fault recorder is mainly used to record power system anomalies' dynamic fault processes.
It is mainly designed to capture and diagnose the changing process of relative
electrical parameters of the power system.
PRS-7973 digital fault recorder integrates multiple functions into one unit,provides transient record- ing,continuous disturbance recording,phasor measurements,power quality monitoring and sequence of events recording.
