Abstract
Now a day’s non- linear load used in industries, result in the harmonics current and voltage in disturbances system. Result in increases NG voltage as well as harmonics disturbances can create a problem to improve power quality. It is important to use fabricated isolation transformer with copper strip which is located between primary and secondary windings of transformer.
Massive buildings and work places have a 3 ph. source where the load is connected with 1ph supply between lines and neutral in a distribution system both linear as well as nonlinear load are present. Due the high harmonic voltage there is failure of equipment and linear load losses. Thus reduction of harmonic voltage is improving power quality.
The main problem in a distribution system is NG voltage. It is nothing but potential measure between neutral conductor and ground conductor. As we know an isolation transformer is used for international safety and standards in electronic equipment has been increased drastically in last several years. Which uses nonlinear load like resistive, inductive and capacitive etc. (rectifier, microwave oven, computer, printer etc.)?Increasing use of power electronic devices there will be a chance of increase in harmonics.
