Abstract
Electric power systems play a major role in modem society and electricity is essential for economic development as well as poverty eradication. A modern power system’s primary function is to satisfy the system load and energy requirements at the lowest cost with a reliable power supply. Therefore distribution systems need to be investigated as they pose the greatest risk to the interruption of supply. Based on the literature review conducted, analysis of historical data on forced outages for populations of medium voltage circuit breakers (i.e., at voltages of 11 kV, 22 kV, and 33 kV) has not received much attention from researchers. In particular, no studies have looked at the medium voltage breaker outage frequency, and duration variables, using chi-square and Kruskal-Wallis tests respectively...
