  • Publication number: 20250348958
    Abstract: The present invention relates to a method for evaluating power distribution networks, the method comprising frequently sampling an electric parameter value representing the electric parameter value of one phase of a feeder from a power distribution station, detecting the sampled electric parameter value passing a first threshold value in a first direction, detecting the sampled electric parameter value passing a second threshold value in a second direction, being substantially opposite to the first direction, determining an event time period as the time period between the two detections of the electric parameter value passing the first and the second threshold value, calculating a ratio between the determined event time period and a circuit action time period, determining an event score based on the calculated ratio between the determined event time period and the predetermined circuit action time period, accumulating event scores over a reliability check time period, and indicating the reliability of the pha
