A Study of Effect of Magnetizing InrushCurrent on Different Ratings Of Transformers

[摘要] Transformer is a very important and major component in power system. It finds a major use in various sectors. In order to reduce the cost and the weight of the core, modern transformers are used at high saturation level which leads to harmonics in the voltage and the current .The resultant harmonics affects the performance of transformer and leads to increase in losses. So for a power system to work efficiently it becomes critically important to asses the harmonics that are generated .In this paper we simulate a power system using MATLAB Simulation. Here we compare the performance of différent rating of power transformers and study the effect of magnetizing inrush current at different switching angle.
