Fault record function:
It will record fault state if the trip command is issued. It also memorizes the fault information
data. The user can see, through LCD screen, several data with additional information: date &
time, fault phase, tripping phase, tripping mode, fault location, operating mode and power
system quantities.
Event record function:
Events related to the IED operations will be memorized in the event record function.
Disturbance record function:
The start of disturbance recorder is triggered by fault detection. The user can see the waveform
recorded by this function using GR-TIEMS.
Automatic supervision
It supervises the health of IED hardware and protection applications during normal operation.
If a failure occurs, the supervise function can issue an alarm and screen the failure information,
such as warnings, problem locations, alarm degrees etc.
