Power Transformers

Contemporary transmission and distribution systems are greatly dependent on transformers. Modern transformers are much more efficient, but much less robust than they were half a century ago. Purchasing, operating and maintenance decisions must be made in order to spend the least amount of money while still yielding the most performance of a unit.

The courses in this area of expertise provide a comprehensive insight into main aspects of transformer design, required testing regime and effective maintenance program. It provides very practical guidance for choosing design parameters, troubleshooting faults and interpreting test results, maintenance scheduling, operational and testing procedures to achieve long service life of power and distribution transformers.


The following courses fall in this group:


TR201 TRANSFORMER CONSTRUCTION

• Transformer's Main components

• Auxiliary equipment and fittings

• Insulation system and cooling

• Transformer manufacturing

• Understanding transformer nameplates


TR202 TRANSFORMER TESTING & MONITORING

• Types of tests and their application

• Field testing: oil, DGA and electrical testing

• Condition monitoring inspections

• Complete physical examination

• Practical guide for interpreting transformer test results


TR203 TRANSFORMER OPERATION & MAINTENANCE

• Aspects of proper transformer operation

• Maintenance program and activities

• Transformer life extension

• Practical guide for transformer maintenance


TR204 TRANSFORMER FAULT FINDING

• Factors influencing transformer reliability

• Types of transformer faults and failures

• Interpreting field and specialised test results

• Practical guide for transformer fault investigation


TR204 TRANSFORMER FAULT FINDING

• Factors influencing transformer reliability

• Types of transformer faults and failures

• Interpreting field and specialised test results

• Practical guide for transformer fault investigation


TR205 TRANSFORMER FACTORY ACCEPTANCE TESTS

• Testing philosophy and categories of transformer tests

• General testing requirements

• Practical guide for planning FAT

• Specifying and witnessing FAT

• Inspections during manufacturing


Engineers that complete the first three courses in this group (TR201, TR202, TR203 and TR204) would obtain skills required to work on power transformer maintenance and would position themselves to become Power Transformer Specialists, by completing additional courses on Tender Specifications (SD301), Transformer Design (SD305), and Factory Acceptance Tests (TR205).

A detailed description of the courses and how they can support your development plan can be found in the program. For more information and for in-house training please contact us on training@matrex-e.com.
