WHY THE FREQUENCY IS 50 HZ IN INDIA.CAN WE USE SOME OTHER
FREQUENCY.IF SO WHAT IS THE RANGE AND WHAT WILL BE THE
EFFECT IN PRESENT POWER SYSTEM IF WE CHANGE THE FREQUENCY
AS YOU SUGGEST ?
Answer Posted / karthikeyan
The reason why in our country we are generating and
distributing the power with 50Hz/sec is, when frequency
increases say 60Hz/sec the losses in transmission and
distribution, transformers and active loads will be high.
economically 60Hz/Sec not affordable in our country.
because copper very high in cost.
