Abstract
Harmonics in the power system are increasing due to increased use of power electronic devices in load. Power electronic devises results in nonlinear loading of the distribution system network creating problem of harmonics. Harmonics effects the distribution transformers in distribution system as well as Power Transformer at the grid substation resulting in more losses, production of extra heat, reduction in efficiency and accelerated ageing of insulation. In this paper a feeder of PSPCL is modelled using EPRI open source distribution system simulator (Open DSS) and effect of harmonics due to nonlinear loading measured from distribution system on the power transformer at grid substation supplying the modelled feeder is evaluated for capacity reduction and loss of life as per IEEE standard C57.110–1998.
