Answer / sanjib pramanick
Generating voltage depend mainly on field
excitation.Generating voltage are 3.3kv, 6.6kv, 11kv like
that because of from factor.We are using sinusoidal voltage
in our system and its from factor is 1.11.

Answer / atreya
generating voltage= (P*B*N*Z)/ (60*A)
where,
P= no. of poles of the m/c
B= flux or excitation given
N= speed of rotation
Z= no. of conductors
A= no. of parallel paths for flow of current
(for lap wound m/c s: no. of paths= no. of poles)
(for wave wound m/c s: no. of paths= 2)

when a 500kva-400hz single phase transformer operated on a 100hz supply then what will be kva required
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.
