Takeover OEL
Takeover overexcitation limiting limits the field current level in relation to an inverse time characteristic
similar to that shown in Figure 11-5. Separate curves may be selected for online and offline operation. If
the system enters an overexcitation condition, the field current is limited and forced to follow the selected
curve. The inverse time characteristic is defined by Equation 11-1.
