Normally erection and commissioning are separate functions, mainly because they require different expertise and therefore different staff. They might be grouped together if the technical requirements of running and testing the particular installation are quite simple.
This technical article deals with transformers and their installation so we restrict ourselves here to the procedures associated with their commissioning. Transformers should be inspected for internal or external damage, particularly if they have been dropped or tipped over.
This should include such items as:
- Drain valves, selector switches,
- Conservator tanks,
- Winding temperature indicators.
