Abstract ? The rise of harmonic on the power system caused by non linear load operation. Harmonic distortion level or called as Total Harmonic Distortion (THD) on transformer potentially cause the increase of losses therefore will be influential on the efficiency of the transformer.In this study was conducted measurement of the THD on one transformers in RSUD Klungkung which then compared with the result of a THD simulation on simulink MATLAB.V based on the result of measurement is 1.51% and result of simulation is 1.49%,I THD on based on the result of measurement is 16.73% and result of simulation is 16.45%. Result of measurement and simulation, it was known that the V THD still meet the IEEE 519-2014 standard, while the I do not meet the IEEE 519-2014 standard. Based on the losses analysis without the influence of harmonic, the obtained losses is 0.62kW. Due to the influence of harmonic causing the increase of losses to be 8,885kW. Based on the results of losses analysis without the influence of harmonic, the obtained efficiency calculation result1 is 99.654%. However the increase of losses as the effect of harmonic influencecaused the decline of efficiency to be 95.048%.
