Settings Example
The overexcitation element is used to de-energize a generator or transformer that is experiencing an
overexcitation condition. Therefore, the manufacturer's overexcitation limit curves are required to
establish optimum protection. Figure 38 and Figure 39 show examples of a transformer and generator
limit curve along with the optimum composite protection characteristic.
Note
Actual damage curves must be obtained from the equipment
manufacturer for the particular equipment to be protected.
