| Summary: | Increases of non linear load on power system will reduce the transformer’s life
expectancy. Distribution transformer manufacturers have been used the rating system called
K-factor to ensure that the transformer can operate safely when suppying non-sinusoidal
load current. This report was provided to show the effect of harmonic on the distribution
transformer from the experiment done to single phase transformer 250VA. The effect of
harmonic was investigated where linear and non linear load was connected to transformer.
The load used in the experiment is pure resistance and rectifier. The experiments were done
to investigate the effect of harmonic to the transformer such as losses, efficiency and
temperature rise. Besides this report was included with the method used to reduce the
harmonic effect to the transformer that is by using the derating method. Two derating
method used is as recommended by standard of IEEE C57.110-1986 and BS 7821. The
results show that there were increases in transformer losses, reduction of transformer
efficiency and higher temperature rise compare to the linear load. |
