Answer / bitm

it is the standard value to manufacture any electrical
equipment in India.

Answer / prathap

because frequence F=PN/120 where p= no of poles and N=speed
so in generating station they maintained constant speed

Answer / swum

1) There are two types of losses
constant loss
variable loss dependent on frequency
So if frequency is increased losses will increase

2) The Indian temperature is higher and hence High frequency
can further heat up wiring.

3) Reduce the frequency the efficiency of transmission lines
will fall

Answer / enggrashmi

its d standard value on wchich electrical equpment are designed to operate...but if we take value othr than 50hz then we have to make our own connections and eqipments...

Answer / sk rafiquil islam (kaithi,jamu

beacause of same frequency is to operate and control many of equipment & its standerds

Answer / nagarajan

Actually we are following British standard
Main reason
1.Atmospheric condition because USA people's using 110v,60Hz so size of the conductor is big one instead of we are using 220v 50hz s0 size of conductor is less and investment also less.
2.Size of conductor increases amount of heat increases.

Answer / anjali singh

For stable ac power distribution , frequency bandwidth is
between 40Hz - 70Hz .Since 40Hz is near to unstable so 50Hz
fequency is standardised in India
