Topics included are transformer fundamentals, transformer ratings, transformer cooling, nitrogen gas systems and insulation systems. The source concludes with in-depth discussions on transformer testing techniques. This course is applicable to technicians and engineers who need a sound understanding of power transformer operation and maintenance.
Students will learn safe and proper maintenance and testing procedures on pad-mounted, power transformers. The course covers transformers used in commercial and industrial power distribution systems, including oil and dry-type units. Larger power transformers used in utility applications are also covered.
Load and no-load tap changer maintenance, ac and dc testing, routine inspections and oil sampling and testing are covered in detail. Students will learn how to perform routine oil tests, and understand how to perform the major tests that are required. A variety of electrical test equipment from various manufacturer’s will be discussed.
And the Following Testing Procedures:
Students will learn:
Part 1. Risk Assessment & Asset Management
This presentation will show how to identify, assess and mitigate the risks associated with distribution and power transformers. Transformers and other electrical equipment are assets that have ongoing maintenance needs or are at risk for failure. The presentation will assist participants in developing an intelligent maintenance program that will evaluate risks and consequences of failure and prioritize maintenance needs according to our data and standards, industry standards and best engineering practices.
Part 2. Introduction to Transformer Testing
Part 3. Increase Transformer Reliability and Life Cycle Through Proper Maintenance of Load Tap Changers
Part 4. Dissolved Gas Analysis (DGA)
How dissolved gas analysis (DGA) results are interpreted – an important tool in the overall transformer maintenance program. Includes hands-on break out groups. This session is intended to identify fault gases and what causes their formation; explain and provide examples of qualitative and quantitative interpretation of dissolved gasses. This class will also evaluate the condition of cellulose insulation and other non-routine tests, and how to determine if a transformer is at risk for failure due to presence of corrosive sulfur, and how to mitigate the risk.
Part 5. In-Service Inspection & Sampling of Fluid-Filled Transformers
Learn how to properly inspect and safely obtain fluid samples from energized electrical transformers. This session is designed for substation personnel whose responsibilities include sampling and monitoring the overall condition of fluid filled transformers.
