Problems Occurs in Power Supply Due to Harmonic Distortion
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 1
Abstract
This paper is written for technical and non-technical people with limited understanding of power conversion technologies who are tasked with specifying, procuring or using power conversion equipment’s for non-linear loads such as:- electronic computer telecommunication equipment’s. A basic explanations of total harmonic distortion(THD) will be provide along with a discussion of sources of current distortion, the effect of power distribution equipment’s, heating effect of transformers and the effects of the other loads connected to the networks. The relationship between power and harmonic distortion is discussed and highlights harmonic distortion as a parameter better representing a figure of merit defining power line and load quality for non-linear loads. Method to reduced total harmonic distortion (THD) and increase power factor is illustrated. Economic consideration and tradeoff between power factor correction (PFC) and low power factor loads is discussed with suggestion applications and conditions not requiring power factor correction (PFC).
