Abstract
Distribution transformers, being the most common equipment in a distribution
system, are of very great importance and must be properly cared for so that they can
perform optimally at all times and last long. One of the major challenges distribution
transformers have is the amount of losses in the transformer. These losses are load and
no-load losses, of which load losses constitute the most under full and medium capacity
operations. Several methods have been proposed in the fight to improve the handling
capacity of distribution transformers and reduce the load losses in the transformer. In this
study, an analysis is carried out on the effects of linear and non-linear loads on an
11/0.415kV, 200kVA, three phase, two winding oil coiled distribution transformers and
three of the methods of loss compensation. These system is modelled and simulated using
Matlab Simulink 2015a. The simulation results are collected and using Microsoft Excel,
graphs are used to compere the results from the different simulations.
