Using a trial and error method of isolating sections of the faulted feeder, crews will reclose the substation breaker to validate that the faulted feeder section is downstream from the isolation point. In this paper, a two-step algorithm for the trial and error procedure is presented, based on the risk assessment of possible scenarios. In the first step, the optimal number of crews is determined, and in the second step, the optimal strategy of section openings and crew with minimum risk is selected. The risk is defined as the product of probability of event and associated non supplied energy. The algorithm is tested on a radial distribution network with 3 sectionalizers.
