Abstract

The substation takes a role as a distributor of electricity from the transmission system to the distribution system and to be distributed to consumers. At the substation, there are transformers that are to reduce the voltage which is from high voltage to medium voltage. There is a safety device which is installed in the transformer, namely arrester. Arrester is a safety device used to protect arresters from overvoltages caused by lightning surges. For maximum protection, arresters must be placed as close to the protected device as possible. The optimum distance for the installation of arresters must be determined so that they can be installed optimally as needed. This study focuses on one transformer and one arrester. The type of transformer used is CG PAUWELS type ORF.60 / 275 and arrester with transformer 1 which is PASSONI VILLA type SCB 170-120 / 150. In determining the safe distance of the arrester installation, we used optimization method by calculating the maximum distance of the traffic with arresters in order to get optimal protection. The analysis obtained from the calculation shows that the maximum distance of the arrester with a transformer is 22.5 m. Meanwhile, in reality, we found that the distance of the arrester with a transformer is only 4.2 m. Eventually, we get the conclusion that the arrester that is installed on transformer 1 is still in the safe box of the transformer since it is still below the maximum distance of the arrester with the transformer.
