Manufacturing Process of 500kVA, 3-Phase Distribution Transformer at Basic Power Engineering Ltd.

Abstract

Basic Power Engineering Ltd. is the pioneer manufacturer of transformers & electrical goods in Bangladesh. The company has always been contributing towards the advancement and development of engineering sector in Bangladesh by introducing a range of quality of distribution transformers with different ranges & other electrical equipment’s likeSwitchgear equipment’s, distribution board etc. I recently have done my internship in Basic Power Engineering Ltd. In which I got training from its transformer section. The internship is basically on manufacturing, assembling, and testing process of distribution transformer. The starting of this report with some fundamental data about introduction, background, objectives and recommendation are shown. Then I have discussed about distribution transformers, its working procedure, its classifications based on its applicability, its efficiency etc. The report includes manufacturing process step by step with core cutting, HT, LT winding, assembling core and coil, tanking up, bushing, oil filling etc. I have tried to describe the whole calculation process of 500kVA, 3-Phase Distribution Transformer with its testing procedure along with test reports which was observed by me. In this report, I have given a very brief review of what I saw and learned during in my internship period. I have mentioned all those things which I have learned in my internship period. This report will give its reader the knowledge about the Basic Power Engineering Limited and distribution transformer. I tried my level best to make the report simple but informative.
