3.4 Configuration A
3.4.1 Applications
Configuration A for non-directional overcurrent and directional earth-fault protection
is mainly intended for cable and overhead-line feeder applications in isolated and
resonant-earthed distribution networks.
The protection relay with a standardized configuration is delivered from the factory
with default settings and parameters. The end-user flexibility for incoming, outgoing
and internal signal designation within the protection relay enables this configuration
to be further adapted to different primary circuit layouts and the related functionality
needs by modifying the internal functionality using PCM600.
