Abstract
A system and method for protecting a power system. A generator is tripped in response to identifying a current on the generator that is greater than a first current threshold for a first time delay. The generator is also tripped in response to identifying the current on the generator that is greater than a second current threshold for a second time delay. The first current threshold is larger than the second current threshold and the first time delay is shorter than the second time delay.
