A substation is an important part of power system where the substation has an important function that is receiving electrical energy obtained from a power source (generator) and substations are working to distribute electricity to consumers. But in the distribution of electricity to the consumer is not easy because of the distance between the substance of the remote consortium to allow for a disturbance both in the form of internal and external disturbances. So to maximize the delivery of electricity and provide reliability of the distribution of electric power it needs an electric power protection equipment in order to feel and minimize the disturbance that occurred. From the above problem, we need a protective device that is over current release (OCR), where this more current relay will work to detect, feel and secure by way of a network when an interruption exceeds the value of the OCR setting limit on the network. In the Final Project with the title of coordination analysis of overcurrent protection protection in the 150 kV Wates Parent where by analyzing the coordination of the protection of more current relay settings installed in the substation and compared with the value of more manual counting settings.
