Application Manual
• Start of any protection function SO1 (X100:10-12)
• Operation (trip) of any protection function SO2 (X100:13-14)
• Operation (trip) of any stage of the overcurrent protection function SO2
(X110:17-19)
• Operation (trip) of any stage of the earth-fault protection function SO3
(X110:20-22)
The two TPGAPC blocks 1 and 2 are timers and used for setting the minimum pulse
length for the outputs. There are four generic timers (TPGAPC1..4) available in the
IED. The remaining ones not described in the functional diagram are available in
SMT for connection where applicable.
Standard configuration F including directional
overcurrent protection with voltage protection
Applications
The standard configuration for directional overcurrent protection is mainly intended
for cable and overhead line feeder applications in isolated and resonant-earthed
distribution networks, where directional protections are necessary to improve the
selectivity of the fault detection. The standard configuration includes phase voltage
and residual voltage protection and measurement and also power and energy
measurement.
The IED with this 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 IED enables this configuration to be further adapted to
different primary circuit layouts and the related functionality needs by modifying the
internal functionality with SMT and PST.
