Abstract :
This paper discusses multi types of overcurrent protection system relays and focuses on the design of a definite time overcurrent relay for three phase system. The definite time overcurrent relay was designed to provide an accurate and reliable system to efficiently protect the distribution system. Overcurrent protection is one type of protection function mostly used for definite time overcurrent protection. Overcurrent protection was used to determine the peak value of the current signals and detect the difference between the normal operation and abnormal conditions to operate just when a fault occurs and disconnect the faulted areas.
