Project

Power transformer maintenance

Project (M.S., Electrical and Electronic Engineering)--California State University, Sacramento, 2018.

Power transformers in a utility grid are expected to work without failure under a wide variety of circumstances, such as times of power system instability, extreme weather conditions, and electrical faults. Because of the extremely high up-front cost to purchase a transformer and its importance as an asset in the utility grid, it is critical for utilities to perform maintenance to ensure reliability, dependability and determine incipient problems that may lead to potential failure.
 The focus of this project is to review and develop an online and offline electrical maintenance testing program for a power transformer.
 This project will analyze the online and offline maintenance tests to trouble shoot a real-world problematic power transformer using various maintenance methods. Engineering analysis on the maintenance data will be performed to create a root cause failure report.
