Figure 40: Alarm indication
The signal outputs from the IED are connected to give dedicated information on:
• 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.
