Abstract:
During my internship, I had gathered practical knowledge of Substations, Voltage Regulators, and Backup Power Systems. I had training on the basic theory behind every product, how the designs are done, how the manufacturing is performed, and finally how the final products are tested in the Quality Control process. These experiences are the content of this report. I have obtained a comprehensive overview of how a power is distributed from grid to the household over the substation. I have achieved hands on experience on Distribution Transformers, Low Tension (LT) & High Tension (HT) Switchgears, Power Factor Improvement (PFI) Plant and Distribution Board. In the process, I have also learnt the use of various types of circuit breakers and protective relays. Apart from substation, I had training on two types of voltage regulators- Auto Voltage Regulator (AVR) and Industrial Voltage Stabilizer (IVS). These two products stabilize supply voltage and ensure safety of the apparatus. I have written my experiences on two types of Backup Power Systems- Instantaneous Power System (IPS) and Uninterruptible Power Supply (UPS). These two products deliver emergency power in the event of power outage from the grid. Sections written on these nine products contain my learning and experience on theories, designs, manufacturing, and quality control process.
