Selected Comments
value
0.00 Typically no additional filtering is required
25 Set minimum voltage level to 25%. Voltage below 25%
will force S, P and Q to zero.
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 magnitude 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 (2000
