Abstract

Harmonics are a phenomenon of voltage waveform deviation
and currents that are transmitted and distributed from source to load in the form
pure sinusoidal waves. This research aims to learn about
the influence of harmonics on distribution transformers in office buildings as well
compare the effect on weekdays and holidays. From the measurement results in
Sudirman Central Business District is known that transformers 1 and 3 exist
harmonics with a current THD percentage of 25.27% and 22.32% on weekdays.
While on holidays there is transformer 1 which has a percentage of THD current
17.24% which exceeds the IEEE 519-1992 allowable limit of 15%.
The dominant harmonics are the 3rd, 5th, and 7th harmonics. With a percentage of THD
currents that exceed the standard limits will result in performance and even degradation
damage to electrical equipment or components. The results of the study show that at the moment
small load (holidays) THD the resulting current is not too large due to the load
less use than during large loads (working days).
