Figure 45: Disturbance recorder
The disturbance recorder has 64 digital inputs, of which 35 are connected as default.
All start and operate signals from the protection stages are routed either to trigger the
disturbance recorder or to be recorded by the disturbance recorder, depending on the
parameter settings. Additionally, the selected autorecloser, the ARC protection
signals and the three binary inputs from X120 are also connected.
Two separate TCS functions are included: TCSSCBR1 for PO3 (X100:16-19) and
TCSSCBR2 for PO4 (X100:20-23). Both functions are blocked by the Master Trip
(TRPPTRC1 and TRPPTRC2) and the circuit breaker open position signal. The TCS
alarm indication is connected to LED 9.
