Answer Posted / man
difference is in the design of rotor being used in these two
cases.
1)In hydro plants since water falls on the turbine ,the
speed of water is less (as compared to steam in case of
thermal plants).
according to the relation, we have
f=(p*n)/120
p= no of poles
f= frequency
n= speed
so in order to have fixed frequency product of 'p' and 'n'
should be a constant.so p should be more(as n is less).
in order to accommodate more number of poles the diameter of
rotor should be large.
2)for thermal we have high speed of steam, so a long core
and small diameter rotor is required to limit the
centrifugal forces developed in the high sped rotor.

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
