Substations Equipments & Load Distribution System of Dhaka Palli Bidyut Samity-01

Abstract

To be a B.Sc Engineer from East West University, we have to take a four credit course as EEE- 498/499 (project/internship). For our graduation we took EEE-499 which is industrial training or internee. We did our internship at Dhaka Palli Bidyut Samity-1. Our internship title is “Sub- Station Equipment and Load Distribution System of Dhaka Palli Bidyut Samity-1” At PBS-1 we have gathered practical knowledge about Power transformer, Distribution transformer, Instrument transformer (both CT and PT), Isolator, Breaker, relay AVR, ACR, ABS etc. Before doing this internship we had theoretical knowledge about Transformer and Switchgear. But now we feel that we have gathered strong knowledge about this Equipments comparing to before. In transformer section we saw the whole process step by step. We learnt how to test a transformer, what the difference are between transformer and instrument transformer we have also learnt the uses of CT and PT and the reasons of using CT and PT at high voltage range. At switchgear part LT panel and HT panel and learnt about types of breaker used for LT and HT panel. We have learnt why power factor is important and how we can improve power factor by using PFI panel. We have also gathered practical knowledge about the use of Circuit Breaker, especially Vacuum Circuit Breaker (VCB).
