Abstract :
Power distribution systems in every company or agency today can not avoid harmonics. Because the current electronic devices with non-linear loads such as computers, printers, energy-saving lamps and so is needed. Non linear load is the trigger of harmonics. Harmonics on power distribution systems can affect the performance of distribution transformers. As the transformer losses increase, the temperature rise and decrease in the capacity (kVA) of the transformer. In this thesis, the measurement of harmonics in Dynaplast Tower and obtained value of THD of phase voltage R is 2,3%, phase S is 2,3%, Phase T is 2,3%. THD voltage does not exceed the IEEE 519-2014 standard value is 8%. THD value of phase current R is 14.2%, S phase is 18.1%, Phase T is 13.6%. THD current exceeds the IEEE 519-2014 standard value of 8%. The fifth harmonic current limit value of each phase exceeds the IEEE 519-2014 standard of 7%. Losses due to harmonics is 9,31 kW at the R phase, 9,826 kW at the S phase, and 8,427 kW at the T phase. Decreased distribution transformer capacity by 13.924% or 139.24 kVA. From 1000 kVA to 860,76 kVA.
