Abstract

Understanding concepts related to the process for determining the design of protection settings requires practical experience, which can be achieved by repeated trials. The objective of this research has described the design and implementation of a hardware simulator for understanding concepts phase and ground fault protection system, evaluate the maximum of short circuit current prospective in the simulator for safe operation, and describe the mechanism of the relay protection operation related to the symmetrical fault and asymmetrical fault disturbance. This paper presents the methodology of the design and implementation of a simulator for overcurrent phase and ground fault protection with microprocessor-based relays. The microprocessor-based relays are used to operate from symmetrical component quantities to demonstrate that any set of unbalanced three-phase quantities could be expressed as the sum of three symmetrical sets of balanced phasors. The result of evaluating the magnitude of maximum fault current at bus substation is 30.84 ampere, at the middle of the line is 11.75 ampere, at the end of the line is 7.3 ampere. The setting of the Instantaneous should be a maximum is 10 ampere. The phase of over current fault will operate phase relay protection threshold for all symmetrical and asymmetrical fault except for open one phase fault disturbance. For ground fault relay operated at one phase fault and all the asymmetrical fault disturbance.
