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
# 1
It is a standard choosen.We can choose some other frequency.
If we change the frequency the power system will be
disrupted,the instruments&appliances has to be designed
accordingly.

Answer
# 2
yes we can choose but the some what high frequncy will
required low volt becuase pressure for electron flow
already affected by high freq. and vice versa

Answer
# 3
if we choose other freequency suppose 60hz ,our standara
freequency is 50hz.for transfer of power there must be same
freequency.Also if freequency increases number of poles
also increases,if poles inc.d diameter of equipment also
inc.it leads to high cost.

Answer
# 4
50HZ is the standard our system has decided, so why you want
to disturb the system?? Your source with about 2% above and
lower than standard freq. can not be synchronized wit the
system.

IN INDIA THERE IS A STANDARD FREQUENCY IT IS 50HZ BUT IN
OUTHER COUNTRYS IT IS 60HZ IT IS STANDARD

Answer

For a Electrical system to get synchronised, one of the
condition to get satisfy is the system frequency.
If frequency to be changed , then it is to be considered
right from power generation system.
While changing the frequency of the stationthe following
factors to be considered.
Frequency = 12o*poles/speed of the machine.
If this frequency factor to get change.....then pole of the
machine and the speed of the machine has to design
accordingly, which is quite inefficient and many factors to
be further considered.

Answer
# 7
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.

in orfer to increase freq. wehave to increase the turbine
speed in power generating station. for that we need some
what more fuel(for diesel turbine) or water (for water
turbine). so it may lead coat effective.

It is a traditional system which has been established. all
the euipments are designed on the basis of 50 Hz so if we
change the freqency all the equipmets get damaged so we can
not change the frequency.

Answer
# 10
Yes we can use another frequency but for this change we have
to change in our power system such as
(1) As we know in generating stations the alternator is used
for producing electric energy and its frequency is given by
f= (Ns)*P/120
where Ns is synchronous speed and P is number of poles so
for increasing the frequency we have to increase the number
of poles which becomes very costly & so uneconomically
And another reason is that we used electrical instrument
which are standardized at 50 hz, 230 v
so we have to also change our electrical systems which are
also very costly
so this is only standard value we can change it but it is
very uneconomical
