Figure 21: Disturbance recorder
The disturbance recorder has 64 digital inputs, of which 32 are connected as default.
All start and operate signals from the protection stages are routed to trigger the
disturbance recorder or alternatively only 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 have been 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.
