Tripping Output - Toshiba GRL100-701B Instruction Manual

2.14 Tripping Output

Figure 2.14.1 shows the tripping logic. Segregated-phase differential protection outputs
per-phase-based tripping signals such as DIF.FS-A_TP, DIF.FS-B_TP and DIF.FS-C_TP, etc.
Zero-phase differential protection, thermal overload protection, earth fault backup protection
and out-of-step protection output three-phase tripping signals DIFG.FS_TRIP, THM-T,
BU-TRIP and OSTT.
