Answer / sam

power can be generated at various Hz, but reason is
equipement are designed for 50 hz and starting itself we
following that frequency of generation(from british
peroid).Changing frequency will affect loads and
equipments.

Answer / jkth

frequency=(no of poles x speed)/120
no. of pole is cnstant.
by varying speed we can change the frequency.
in india 50Hz is used.
in Canada,Antigua,Bermuda,Colombia,Brazil,Cuba,Mexico etc. 60Hz is used.

Answer / santhoshkumar

No, power can be can be generated at diffrent frequencies
by setting the speed by Generator governer control

Answer / aldossary

Freq. can be changed easally but fixing this value to 50
or 60 Hz is very important to design the
generators ,transmission control and end ueser equipments.

Answer / zeidan

beacuse the lowest freq at which we can sxx light constant
is 50hz hence as the freq increase more than 50 is better

Answer / prince kumar meshram

because at this frequency the efficiency of the generator
is maximum in our india
from the fomula
frequancy= (no. of poles*speed)/120
where the no. of the poles is constant

Answer / shivam

when we can do this, as u say, then why we dont do this.
because it is said that efficiency increases on increasing
frequency. plz help me out
