how calculation to be done of cable size/o.h. conductor
size of 11kv h.t.for the load of 2175 kw
Answer / k.prakashchandra
The current is about 120 A. But it is not continuous.You
have to the study the list of OH conductors available in the
market.For 120 A and 50' Temp rise ,weasel ' ACSR conductor
is enough. Then you have to consider voltage regulation
which should not exceed 6% and further development. Rabbit
ACSR conductor is the next one with carrying capacity of 148
A for 30' temp rise and 183 A for 50 ' temp rise.Temp rise
is for calculation of maximum sag.

What conditions are required for a transformer to operate at low frequencies ?
what is meant by brushed alternator & its working principle ?
i am using auto transformer for starting of induction motor to provide reduse voltages...but the principle of a tansformer according to definition"which transform energy to on circuit to another circuit with constant power and constant frequency". so if i am using reduse voltage then current obsely hige because power is same.but we use auto transfarmer for starting of induction motor to give low current.but here according to definition we are giving hige current.
How does frequency affect KVA rating of a transformer? If a 500 kva, 500 to 250 v, 60 hz t/f normally used in Canada is to be operated in Europe on 50 hz frequency then how will its KVA rating change? a-increase b-decrease c-remains same
