Module: Protection (Prot)
General Alarms and General Trips
Each protective element generates it´s own alarm and trip signals. All alarms and trip decision are passed on to the
master module
»Prot«.
If a protective element picks up, respectively has decided about a trip, two signals will be issued:
1. The module or the protection stage issues an alarm e.g. »I[1].ALARM« or »I[1].TRIP«.
2. The master module
»Prot«
collects/summarizes the signals and issues an alarm or a trip signal
»PROT.ALARM« »PROT.TRIP«.
Further examples: »PROT.ALARM L1« is a collective signal (OR-connected) for all alarms issued by any of the
protective elements concerning Phase L1.
»PROT.TRIP L1« is a collective signal (OR-connected) for all trips issued by any of the protective elements
concerning Phase L1.
»PROT.ALARM« is the collective alarm signal OR-ed from all protection elements.»PROT.TRIP« is the collective alarm
signal OR-ed from all protection elements.
