Abstract
Percentage of maximum loading on distribution transformers according to the provisions does not exceed 80% of the capacity of the transformer. If the loading is more than 80%, it can disrupt the quality and continuity of the distribution of electric power to consumers. The analysis aimed to: determine the amount of voltage drop and power loss that occurs before the installation of the addition electrical distribution substation. The analysis done by taking a case study on existing distribution substation (named MRK 051), its have 4 (four) electrical line services (line A, line B, line C and line D) and addition electrical distribution substation (named: MRK 267) at Muli feeder in PT. PLN (The National Electricity Company) Region Merauke. Impact of addition electrical distribution substation was conducted by using analytical mathematic to compare two variable: drop voltage and power losses. The result revealed that: drop voltage at MRK 051 before addition electrical distribution substation allocation are valued meanly more than 10% and power losses are 1,22 kW (kilo-Watt) at line C. After addition electrical distribution substation allocation, drop voltage reduced to smaller than 10% and power loss reduced to 1,06 kW (kilo-Watt) at line C.
