|For polarity test on a 11/3.3kV 2.5MVA delta-star Unit
Auxiliary transformer,415V 3-phase supply was applied at
the HV. Connection between Aa was made with a 2.5mm cable.
As soon as power was switched on the cable caught fire and
burnt. This test was then abandoned. It is noteworthy to
say that a similar cable was also used in a similar
transformer for the same. The cable did not burn and test
was successfully completed with good result. What is wrong?
Please, help me out.
