Abstract
A controller-based detection system configured to adaptively learn to distinguish between detected light that is indicative of an arc fault event and detected light that is not related to an arc fault event. In particular, the detection system is configured to observe the electrical power system as it is operated under various conditions to induce light events that are unrelated to arc fault events. Using the observed information about the light events that are unrelated to arc fault events, the detection system determines one or more detection algorithms. During normal operation of the electrical power system, the adaptively determined one or more detection algorithms are utilized to identify arc fault events in the electrical power system.
