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.

A method for residual overcurrent protection comprising:
- determining an increment amount for residual overcurrent protection;
- determining a decrement amount for residual overcurrent protection;
- determining a count value based at least in part on the increment amount, the decrement amount, and a previous count value;
- detecting an overcurrent condition based at least in part on the count value and a residual overcurrent limit;
- and
- controlling a generator to correct the overcurrent condition responsive to detecting the overcurrent condition.
An aircraft comprising:
- an electrical load;
- and
- a generator to generate electrical power and supply the electrical power to the electrical load, the generator comprising a controller to:
- determine an increment amount for residual overcurrent protection;
- determine a decrement amount for residual overcurrent protection;
- determine a count value based at least in part on the increment amount, the decrement amount, and a previous count value;
- detect an overcurrent condition based at least in part on the count value and a residual overcurrent limit;
- and
- correct the overcurrent condition responsive to detecting the overcurrent condition.
