engineering colleagues. At the end of this course, the candidates 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.
This course aims at providing a comprehensive understanding of principles of
operation, types, selection, testing and commissioning, protection, maintenance
and troubleshooting of electric power and distribution transformers.
