This presentation will discuss the processes involved with oil-filled transformers including those of:

• Receiving a transformer after transport to a substation site
• Assembly and processing of a transformer at site
• Testing of a transformer to verify its suitability for service
• Discussion of integrating the transformer into the power system

Transformers are required in almost every power supply situation. The installation and testing of the transformer verifies its condition at the time it is ready for service as well as forming the baseline or signature tests for all future maintenance and later condition assessment or analysis.

The manner and processes that are used to receive, assemble, process and test the transformer are of fundamental importance to the long life of the transformer.
