10 ANALYZING EVENT AND FAULT RECORD
10.1 Overview
The ADR211A Single Pole Relay provides several tools (listed below) to analyze the cause
of relay operations. Use these tools to help diagnose the cause of the relay operation and
more quickly restore the protected equipment to service.
1. Event Recording
2. History Faults Recoding
All reports are stored in non-volatile memory, ensuring that a loss of power to the ADR211A
will not result in lost data.
10.2 Event recording
ADR211A relay is providing feature to record and store events in non-volatile memory
through internally by protection and control functions and can be extracted using
communication port. The event shall be trigger on time stamp through time synchronization
or internal clock setting.
10.3 History Fault recording
ADR211A relay is provides built in history fault recording facility for recoding the fault with the
current, symmetrical components parameter value. Relay records history fault and stored in
to non-volatile memory.
