Analysis of Distribution Network Losses of Nr.04 Feeders At Namorambe Substation (PLN ULP Johor Case Study)
Keywords:
Transformer, Power Losses, Efficiency, Electric PowerAbstract
Efficiency is one of the important aspects in transformers to optimize the distribution of electrical energy. The study analyzed and tested losses in transformers. This test was carried out by measuring the voltage, output current of the transformer each day and night. The results of the study showed that the losses incurred included, the peak load that occurred at night was 32% and during the day was 2.04%. The value of power losses caused by neutral current during the day was 0.037 kVA percentage of 0.02%, while at night it was 0.346 kVA with a percentage of 0.22%. Power losses due to grounding current during the day were 0.256 kVA percentage of 0.16%, at night it was 0.586 kVA with a percentage of 0.3%, kWh saved at JTM was 124.2209 percentage of shrinkage reduction in JTR after being balanced, at peak load conditions of 84% and outside peak load conditions of 73%. Based on the results of the analysis, the transformer tested is suitable for use and the losses are still within the SPLN standard limits.
