Power and distribution transformers are among the most expensive and hardest-to-replace assets in any electrical system. This course gives you a practical, standards-based method to inspect, test, diagnose and maintain liquid-filled and dry-type transformers, from industrial distribution units to large substation power transformers. You will learn how transformers fail, which tests reveal developing problems, and how to turn test data into sound maintenance, repair and life-extension decisions.
This 12-hour, instructor-led course is for anyone who maintains, tests, specifies or manages transformers in utility, industrial, commercial and data center facilities. Participants who complete the course receive a certificate of completion and 1.2 CEUs.
Transformer lead times now stretch to two to four years for many ratings (VERIFY), and replacement costs have climbed sharply. An unplanned failure can mean an extended outage, a costly emergency rental and serious safety and environmental exposure. Keeping your existing fleet healthy is no longer optional; it is a core reliability strategy.
NFPA 70B makes electrical equipment maintenance an enforceable requirement. Facilities must run a documented electrical maintenance program (EMP), assess equipment condition and set maintenance intervals based on that condition. Transformers are central to that program, and the standard expects qualified people to perform and interpret the work.
Modern diagnostics, including dissolved gas analysis, power factor and dielectric frequency response, sweep frequency response analysis and online monitoring, can detect most developing faults long before failure. The value comes from knowing which tests to run, how to run them safely and how to read the results correctly. This course delivers that knowledge.
This course combines engineering fundamentals with real field data and case studies.
By the end of this course, you will be able to:
Participants leave with a structured approach to transformer condition assessment that they can apply immediately at their own facilities.
The course is taught by [name], a transformer testing and maintenance specialist with extensive utility substation engineering and field experience.
Each module combines engineering principles with field photographs, actual test reports and failure case studies. Live polls after every module reinforce key concepts, and interpretation exercises let participants work through real DGA, power factor and SFRA data the way a test engineer would.
Participants receive the course slides, a participant workbook, a transformer test acceptance checklist and a maintenance interval matrix template to support their own maintenance programs.
