		abstract={Transmission system is a system of distribution of electrical energy from one place to another, such as from power station to substation. Disturbance in transmission
line such as: three phase short circuit, two ground phases and one phase to ground. Protection system is needed to neutralize the disturbance that occurs in the transmission system. One of the protection systems used to neutralize the
disturbance with a distance relay. This distance relay measures the voltage at the relay point and the disturbance current seen from the relay, by dividing the magnitude of the voltage and current, the impedance to the point of occurrence of the disturbance can be determined. The distance relay will work by comparing the measured interference impedance with the impedance setting. The basic principle is based on the characteristics of the distance protection distance measurement disturbances that can be set up more than one zone of protection. The first is zone
1 with a short trip time, then zone 2 protection, zone 3 and so on, with a slower trip time. According to the results of its calculation of the range of impedance relay for
zone 1 is 24.8732 ?, for zone 2 of its 47.354 ?, while its zone 3 ? 70.85028. If the impedance value obtained exceeds the impedance value setting, then the distance relay will give a warning so that the feeder is broken will break up with PMT.}
