Abstract: An example method for residual overcurrent protection includes determining an increment amount for residual overcurrent protection. The method further includes determining a decrement amount for residual overcurrent protection. The method further includes determining a count value based at least in part on the increment amount, the decrement amount, and a previous count value. The method further includes detecting an overcurrent condition based at least in part on the count value and a residual overcurrent limit. The method further includes controlling a generator to correct the overcurrent condition responsive to detecting the overcurrent condition.
