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 ±Δdb=40 MW that is, 2% (larger changes
than 40 MW will be reported)

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.
