Abstract

Transformer power is a very important piece of equipment for the distribution of electrical power so that the need for protection to work remains a reliable. Protection system is a form of protection on electrical equipment to avoid damage to the equipment as well as maintaining the stability of the electric power distribution. Protection equipment used one that is relay differential. The function of the differential that is relay secure transformer short circuit of the disorder that occurs in the internal. Differential relay is a relay which is a work based on the difference of the current through the security area. The right setting of differential relay on very influential towards works of a good protection system. The methods used to determine the differential that is relay settings by getting secondary data by doing research on Substation Wonogiri and looking for a journal reference in accordance with the research conducted. Further processed data obtained by the calculation manually. Calculations performed in the form of currrent value ratio transformer (CT), the calculation of parameters in case of differential rele without interruption, followed by the calculation of the value of the parameter differential rele occur the presence of interference. The results of the CT ratio values obtained at the side of the 150kV namely 300:1 and on the side of 20kV namely 2000:1. Differential current acquired for 0, 16A obtained from the difference between the value of the secondary flow on the current transformer (CT) of 1, 33A on side 1, and 49A 150kV on the side of 20kV. The current setting values acquired for 0, 16A. Expected from such settings on the power transformer protection system capable of operating with a reliable.
