Why in india freq. is 50HZ & in U.S.A. it is 60HZ?

Answer / sri244
Yes India freq. is 50Hz,because of our started electricity in 1902 in SIVASAMUDRAM from Karnataka.That is 4.5 mega watts. so
on that time we are choosing 50 cycles per second.But in u.s.a. it is 60HZ there is small power losses occur.NOw in India we change in 50HZ but it is not possible. So that's way we are using "power factor improved techniques".So this technique used to minimise power lossess.

Answer / m.kumaran
Normally the formula for speed is N=120f/P
N=Speed in RPM
f=Frequency
P=No of poles
Example
f=50Hz
P=2
so N=3000 RPM.but we use 4 pole machine we get 1500 RPM
The indian machines are manufactured only 2&4 poles only so
we get 50Hz frequency. but most of indian power generating
stations are follow this technique. but we want to change
this method total methods of generating station will de
changed.

What mean by MLTP
I want to put this query to SENIOR & EXPERIENCED ELECTRICAL ENGINEERS. 1)I want to know about the control circuit diagrams for control panels. I found it difficult to understand. Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer? How to enter this field? I need job in PUNE
why power is generatd at 50 hz only..? can we do this on another freq...?

1))why we run three phase or three different circuit from a single conduit 2)) why not two circuit of different phase run in same conduit?? and why we run same three cicuit of same phae run in single conduit??
what is resver in electrical enginnering with answer
at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
