basically the difference is in there cooling system,voltage
level and core material.
the core of power transformer is made up CRGO where as the
core of distribution transformer is made up of silicon steel.
generally the voltage level of power transformer is above
33kv and for this we use ONAF COOLING means we suppliment it
from fan for cooling and in distribution transformer
radiator is sufficient for cooling.

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.
