With good coordination of protection systems would minimize local disruption and outages in other areas so that the protection system should have protection requirements that have been specified are: reliability, speed, sensitivity and selective. By analyzing and reviewing the working order of safety equipment along the channel of the resource to load is expected to prevent or limit damage to the network and its equipment. In connection with the importance of the reliability of an electric power distribution system. Then this paper will discuss the overcurrent protection system on the network medium voltage 20 KV At Soekarno ? Hatta airport relating to the supply system for technical Network North Ring.} }
