EXAMPLE OF IDMT OVERCURRENT PROTECTION CURVE
NOTE:
The IDMT overcurrent protection is Breaker open and cool down (BOC) type.
This setpoint adjusts the threshold level for the generator overvoltage protection.
The threshold is adjusted in % of the nominal generator voltage, which is either
GenNomV or GenNomVph-ph, depending on the position of the setpoint
FixVoltProtSel.
The protection activates if the voltage in at least one phase gets over the
threshold for time longer than Gen V del.
NOTE:
The asociated protection to this setpoint is Breaker open and cool down (BOC)
type. There is also Shutdown overvoltage protection, which is adjusted by setpoint
Gen >V Sd.
NOTE:
The BOC protections are active after the Max stab time elapsed or after the GCB
was closed, then while the GCB is closed and then also during cooling (if Cooling
speed = NOMINAL).
