3.5 Standard configuration L
3.5.1 Applications
The standard configuration for directional overcurrent and directional ground-fault
protection with phase voltage-based measurements, undervoltage and overvoltage
protection, frequency protection and measurement functions is mainly intended for cable
and overhead-line feeder applications in isolated or resonant-grounded distribution
networks. The configuration also includes additional options for selecting ground-fault
protection based on admittance, wattmetric or harmonic-based principles.
The protection relay with a standard 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.
Standard configuration L provides the highest functionality level of REF615 standard
configurations supporting sensor inputs. Standard configuration L is delivered
preconfigured with directional overcurrent protection but it also supports non-directional
overcurrent protection as well as directional overpower. Depending on the specific feeder
application, the appropriate functionality can be selected and an own configuration
