Abstract :
Nonlinear load is the cause of harmonics that can affect the decline in the quality of the electric power system, especially can cause losses to the distribution transformer. In this thesis harmonics measurements were made on senopati 2 feeders in Gambir Lama GI and the results of current THD values exceeded the SPLN D5.004-1: 2012 standard were 5%. While the results of the voltage THD value does not exceed the SPLN standard D5.004-1: 2012. Based on the calculation of the values of distribution transformer losses obtained on November 1, 2019, R phase 48.35 KW, phase S 45.66 KW, phase T 64.35 KW. On November 2, phase R 37.58 KW, phase S 37.59 KW, phase T 42.95 KW. On 3 November 2019 phase R 21.32 KW, phase S 24.23 KW, phase T 25.80 KW. So the harmonic effect causes a decrease in transformer efficiency to be 82.07%.
