value
25 Set minimum voltage level to 25%. Voltage
below 25% will force S, P and Q to zero.
3 Set minimum current level to 3%. Current
below 3% will force S, P and Q to zero.
400.00 Set rated OHL phase-to-phase voltage
1000 Set rated primary CT current used for OHL
1000 Set based on rated Power

value
-100 Minimum expected load
100 Maximum expected load
3000 Set zero point clamping to 60 MW that is, 3%
of 200 MW
db Select amplitude deadband supervision
2000 Set ±Δdb=40 MW that is, 2% (larger changes
than 40 MW will be reported)
60 High alarm limit that is, extreme overload
alarm, hence it will be 415 MW.
50 High warning limit that is, overload warning,
hence it will be 371 MW.
-50 Low warning limit -500 MW
-60 Low alarm limit -600 MW
1 Set ±Δ Hysteresis 20 MW that is, 1% of range
