Abstract – This paper is about the analysis of a simple 220/440 distribution network by implementing a power analyzer in the distribution transformer. This analyser logged in the system for a certain duration of four hours and recorded the parameters like voltage, current, power, active and reactive power of all the three phases. The average of all the voltage and current unbalance has been calculated and harmonic distortion of voltage and currents also been measured for the comparison of harmonics with the permissible range. As the networks consisting of nonlinear loads and due to this harmonics increases in the system. So a solution has to be find out like active power filters to be include in the system and to reduce the harmonics up to the permissible limit. The harmonic distortions are compared from the IEEE standards and after implementing the solutions the distortion should not exceed the maximum value for both voltage and current.

Key Words:  Total harmonic distortion, non-linear loads, distribution transformer, linear-loads
