 Integrated
Protection SystemŽ
- Voltage Collapse Mitigation providing 4-step undervoltage and 4-step
underfrequency load shedding functions
- Undervoltage blocking and negative sequence overvoltage blocking for
system faults provides load shedding security
- Local and remote serial communications for monitoring and control
functions
- 5 programmable outputs and 2 programmable inputs
Protective Functions
- 4-Step Phase undervoltage (27) protection, single-phase and positive
sequence
- 4-Step Phase undervoltage, selectable as single phase or positive
sequence responding, with Negative sequence overvoltage and single phase
undervoltage supervision
- Phase overvoltage (59) protection
- Four-step over/under frequency (81) protection
- Rate of Change of Frequency (81R) protection
- IPSlogic™ takes the contact INPUT status and function status
and generates OUTPUTS by employing (OR, AND, and NOT) boolean Logic
and a timer.
