PLN as the company that manages the supply of electricity is always trying to improve the availability and reliability of electricity for consumers. Protection on the transmission line will determine the reliability of electricity that needs serious attention in planning is no exception setting is relay protection equipment. Rele rele distance is most widely used as the primary safety on High Voltage Air Channel. The data used to determine the distance relay settings such as the type of data conductors CT, PT and determine L1, L2, L3. Based SPLN shared security zones, namely Zone 1, Zone 2 and Zone 3. Determination of the zone using this data. Based on the relay setting calculations that have been done there is a difference with the setting-Duri Kosambi assisting Cengkareng. However, taking into account the errors of the data kostantasaluran, CT, PT and equipment other 20% is still within the scope of SPLN} }
