VOLTAGE PROTECTION WITH LOAD SHEDDING SCHEME BLOCK WITH MICOM P923

Application:-
1. Comprehensive voltage protection with Load Shedding Scheme

Protections:-
1. Undervoltage, 3-stage, DT and IDMT
2. Overvoltage, 3-stage, DT and IDMT
3. Zero-sequence overvoltage, 3-stage, DT and IDMT
4. Negative sequence overvoltage, 2-stage, DT and IDMT
5. Positive sequence undervoltage, 2-stage, DT and IDMT
6. Under- / overfrequency, 6-stage
7. 6-stage df/dt (P923 only)
8. ΔU/Δt (P923 only)
