Harmonic Current Effect on Three Phase 100kVA Transformer Losses under Static Load and Dynamic Load

Abstract:

This paper describes the harmonic current effect under static and dynamic load on 3 phase 100kVA transformer model. The methodology that used to measure a harmonic current is using power analyzer with different excitation. The experiment is conducted by changing input voltage with different flux density. A waveform can be obtained by using the data collected. 3^rd order of harmonic gives a high impact to the complex waveform. At 0.6 Tesla, 50 Hz, the 3^rd order of harmonic current under static load and dynamic load is 0.00196A and 0.26746A respectively. Therefore, both static and dynamic load were give an effect to harmonic current effect on transformer. This is because when the transformer connected to the load, more current and voltage induced in order to energize the load. Moreover, the loads itself have their own harmonic effect because of the functional mechanism.
