Abstract

Disorders that exist in the distribution system occur due to various factors, namely internal factors and external factors. For external interference itself there are overload disturbances and also short circuit interference caused by natural disturbances. This will cause a very large current that can damage the electrical equipment that causes the outage of electricity to consumers. For this reason, the electric power distribution system requires a protection system to separate equipment that has been disrupted. In this thesis the disturbance that will be calculated is a two phase short circuit interference and one phase short circuit interference to the ground by using per-unit(pu) method. In GIS Kota Timur there is a 60 MVA power transformer with a voltage of 150/20 kV. In this transformer, only the Dayung feeder will be evaluated, where the feeder uses a conductor of A3C 150 mm2 and NA2XSEBY 240 mm2. Overcurrent relay for feeder is set with TMS 0.14 while ground fault relay is 0.12. In the 150 kV side transformer, overcurrent relay is set with TMS 0.33 while the ground relay is 0.1. In the 20 kV side transformer, overcurrent relay is set with 0.19 TMS while 0.07 ground fault relay
