Abstract :
This paper proposes the design of an algorithm to detect fault in underground cable for blocking auto-reclosing in distribution feeder of Metropolitan Electricity Authority (MEA). The algorithm consists of two major steps. First, overcurrent detection algorithm is applied to compare fault current with current setting. Next process, the impedance detection is used to identify the fault location base on comparing between the measuring and the setting of impedance value. Finally, these results (current & impedance) are used to make a decision of auto-recloser blocking. This paper also shows the results from software simulation and hardware simulation.
