This course builds from foundational to a more advanced understanding of managing a transformer maintenance program and plan. Since 1975, this course has stood the test of time and has benefited thousands of people who are competent, confident and reliable.
- Transformer Basics: Historical survey of transformer development and application. What does the transformer consist of, what can go wrong, what maintenance is required - and why?
- An Introduction to Transformer Oil: Changes in the oil industry over time that are not apparent. The need to know what these changes are and why they are important. The effects of an electrical field and other aging accelerators on the oil. What causes the oil to go bad? What can you do to control the process?
- Testing Transformer Oil: The meaningful in-service tests. Why test the oil? What do the tests tell about the oil?
- Water in Transformers: Determine how wet is “too wet”. What to do if your transformer is wet?
- Monitoring and Diagnostics: Dissolved Gas Analysis (DGA) and Furanic Compounds: What faults cause gassing? After the analysis, how do you diagnose the problem?
- Factory Electrical Tests: Why, when and how they are done?
- Field Electrical Tests: What do the results mean? A practical exercise is included in this session.
- How Transformer Life is Measured: How long should a transformer last? What effects do heat, water, acid and oxygen have on transformer life?
- Interpreting Transformer Oil Test Data: What does the test result data mean? What steps should be taken and why? What actions are called for at what limit values?
- Maintenance Options: The “why,” “when” and “how” of reclaiming. Why not replace the old oil with new oil? Beyond reclaiming the oil - how do you clean the transformer? This section will also explore dehydration techniques and load tap changer maintenance.
- Fluids other than Transformer Oil: This session will give you information on fluids other than mineral oil.
- Developing a Maintenance Program: Putting it all together in terms of maintenance and recommending a proper course of action with the end result being “LIFE EXTENSION” of your system
