ePROT 201: Distribution System Protective Devices

This complimentary eLearning course introduces distribution-level protective devices that are used to minimize fault duration, outage impact, and equipment damage. It describes the role of fault-interrupting devices (i.e., fuses, breakers, and reclosers), recloser controls, protective relays, and sectionalizers as well as the device coordination process, overcurrent elements, and time curves.
