Answer / shahed

earth to neutral voltage can be due to
1. improper or no earth
2. neutral currents flowing
By proper earthing techniques 1. can be solved.
For 2. the neutral current must be reduced . If possible
the rating of the neutral conductor can be increased therby
reducing IR drop. or an isolation transformer may be used
with it's secondary neutral connected to earth.

Answer / shailendra

1 Answers   Hydropower,

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.
