- In power system, the protection system is an important somponent to maintain the continuly and reliability of electricity distribution. Protection system serves to protect the equipment from damage in the event of interference as well as to avoid widespread disruption to localize. In this case the protection system used is the differential protection relay in 30 MVA power transformers at substations boom baru. The workings of the differential relay is a way to make the current setting is graeter than the differential current relay because it includes the percentage differential relay. Based on the results of the calculations heve been done magnitude of the differential current is 0,21 A and stting current is 1,3 A. So Isetting > Id, so that relay will not work and the system is in normal state. With this tool, we can realize the expected power system more secure in terms of security and reliability that do not harm humans and the environment, as well as minimize the risk of damage to electrical transmission. Keys Words : protection system, differential relay, setting current, differential current
