3.3 ACCEPTANCE PROCEDURE
Upon arrival of a transformer and its accessories everything should be sure closely inspected.
The following points should be checked before acceptance:
• Is there any damage on the crate or box?
• Is there any rust or is the paint on the transformer or its accessories damaged?
• Are the transformer tanks or accessories damaged?
• Are there any oil leakage?
• Are bushings of H.V or L.V damaged?
• If the oil level is visible: is it high enough?
• Is the delivery complete?
• Check the number of transformers, the number of boxes of accessories and check that all
accessories are fitted or present.
• Check the information on the nameplate.
• Is the paint of tank damaged?
3.2 TRANSPORTATION BY RAILWAY OR SEA
Transformers are usually packed in strong crates, boxes or containers. When packed in crates,
the transformer’s lifting lugs can be used to lift the entire equipment.
Under no circumstances may moisture be allowed to penetrate into the transformer. For
hermetically sealed transformers - both those with gas cushions and those with integral
filling – this is not a problem. The liquid cannot come into contact with the surrounding air. For
transformers with an expansion tank the infiltration of air during transportation and storage is
prevented by: either placing a gasket in the de-aerator (breather) (which must be removed before
the transformer is energized) or replacing the silica gel air breather with a blind flange that
prevents the infiltration of air. In that case the air breather is supplied separately. Assembly
instructions are included with the air breather.
All deviations should be reported immediately to the manufacturer. If no report has been
received within one week of the delivery, we shall assume that the delivery arrived complete
and in good condition.
