Manufacturing and Testing Process of CT-PT, Power and Distribution Transformer, Switchger, Breaker and Isolator.

Abstract

We did our internship at ENERGYPAC ENGINEERING LTD, S/\VAR, BARUIPAR.\ from 31" May to 29th June and this internship report is the result of that two weeks attachment with that company. We have observed and learned those things practically which our teachers taught us in the class Energypac Engineering LTD. primarily manufactures substation equipment such as transformers and switchgcars etc. In this report we have focused on various types of machines. Various no of tasks were implicated to make a transformer.among those most of the tasks were introduce to us. Most of the raw materials come from abroad to manufacture a transformer. We were shown the making of transformer coil, which depends on the transformer power rating. We also also shown the assembling and internal connection setup of the transformer, including cooling system tank making and painting. After the manufacturing how those equipment is being tested this is also showed to us. Another important feature is the testing facility of ENERGYPAC ENGINEERING LTD. To ensure the best quality they test all their manufactured equipment. There are various types of test like magnetizing current test, high voltage test and special type test. These tests are done only at ENERGYFAC ENGINEERING LTD.
