Answer / aswath

1 ton = 3.5 kw,so 2 ton =7kw,
2 ton ac draws 30 A, i.e 6.9 KVA
For 125 KVA,each phase 125/3=41.67 KVA.
For each phase connect 6no's of AC.totally 18 no's.

Answer / k.prakashchandra

A 2 ton may draw about 15A i.e. 3.45 KVA.Each phase of Tr is
of 125/3 =41.67 KVA .AC per phase is 12 totaling to 36

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.
