Installation, Testing and Troubleshooting of Transformers

THE WORKSHOP

This will provide you with practical knowledge (including tips, tricks and tools) covering the fundamentals of power transformers and their testing. It will greatly assist you in communicating more effectively with your electrical engineering colleagues. At the end of this workshop, participants will be familiar with the importance of transformer testing and their purpose, the different kinds of transformer tests and their procedures and the practical applications of principals applied in transformer operation and maintenance.
