The impact of covered overhead conductors on distribution reliability and safety

A modern electric distribution system must provide a certain level of reliability for customers. In addition, decreasing the harm to life due to accidents associated with distribution systems should receive considerable attention. For overhead distribution systems, the reliability of covered overhead lines could potentially be improved using various alternative technologies. The statistical two-sample t significance test presented in this paper can be used to determine the cause-and-effect relationships that exist between the covered rates and the reliability indices including public safety. Moreover, because outage events occur at unpredictable times and for different reasons, the Monte Carlo simulation approach (MCSA) is a useful method that can use a computer to rapidly generate a large number of trials that simulate outage events. The MCSA is applied in accordance with the strong law of large numbers to obtain reliability and safety indices for a distribution system. A practical test system is employed to analyze and simulate the reliability index and safety index results.
