This course will serve anyone who is invloved in the decision making processes in the transformers industry, substation management and to high-level tech experts such as foremen, job leaders, etc.
The L2 Transformer Condition Assessment Course offers a comprehensive learning experience for professionals working with oil-filled power transformers and substation diagnostics. This course consists of 13 lessons designed for individuals at different levels of expertise.
Basic Level: The course begins with an introduction to transformer condition assessment, covering key technologies and processes to evaluate transformer health.
Key topics include the importance of benchmarking equipment, making critical decisions based on data, understanding partial discharge, vibration, and sound analysis, and applying severity criteria.
Intermediate Level: Vibration and sound analysis help assess transformer conditions and cooling systems, with a focus on oil circulation pumps and main windings.
Partial discharge detection through acoustic emission is explored to identify electrical leakage and arcing in transformers.
Infrared thermography is introduced to detect hot spots in transformers and their components.
Master’s Level: Advanced lessons dive into the analysis of transformer conditions, including detailed vibration analysis, partial discharge detection, and oil quality testing.
The course provides hands-on training with virtual sessions to enhance practical understanding, especially for vibration and sound testing of transformer components.
Participants will learn diagnostic techniques, data interpretation, and how to implement these tools to improve transformer maintenance and performance.
