Impacts of harmonics on step-down transformer are presented in this paper. Transformer failure had been reported due to harmonic current causing excessive winding temperature rise. Excessive temperature rise of transformer is due to harmonic effect result in higher power loss than normal operating mode. An experimental setup is proposed which allow for observation of harmonics. This research focuses...
The harmonic power losses cause increased operational costs and additional heating in power system components, which will reduce their expected lifetime. This is especially in the commercial building, where the usage of power is very high as there are many large scale types of equipment being used. This paper presents the effect of harmonic current distortion on the transformer useful life, K-factor...
Proliferation of harmonics in power distribution systems, which are using increased nonlinear loads, have become a power quality problem for both customers and suppliers. The harmonic power losses not only cause an increase in operational costs but also create additional heating in power system components, which in turn will reduce their life expectancy. This happens especially in commercial buildings,...
