Answer / shahul snfa

if we use 230v,50hz for a load say 100kw. the current for
this supply will be small when compared with 110v,60hz. but
the cable size for 110v,60hz is large due to insulation
size. an most interesting thing is only the cold countries
will use 110v,6ohz supply because the heat dissipated due
to large current will acceptable to their climatical
condition but not for india.. so the supply is depended
upon the country climatical condition and about adv &
disadv........

Answer / manikiran

High Frequiencies generate High Synchronous speeds and low
voltage means that low Ironlosses....Where as the High
voltage transfer more power with same loss in the line when
compared with a Low voltage line

The Problem Here With Power Consumed in Loads
If We Have A 220KW Load
We will Use Cables That Can Cary 1000 Amperes When Using 220
Volt Suppl .y
While We will Use Cables That Can Cary 2000 Amperes When
Using 110 Volt Supply .

So The Characteristic Of Each Cable Is Changed With the
Supply .


on the other hand the (I^2)(R) Consumed in Cables will Be
High with 110 Volt Supply .

Answer / s c budhiraja

With 230V 50Htz supply;advantage: Smaller conductor size
for same power Disadvantage: higher danger of eletrcution

With 110V 60Htz supply,the advantage is less danger of
electic shocks but bigger size of conductor for the same
power

Answer / maheshwaraih

because for current saving purpose

Answer / prabakaran

The cold countries only using 110V,60HZ. Because they are need to save the machines. The cold will affect the machine parts. loss is high, so they can avoid this affects should be machine can run maximum speed. The maximum speed only increase the heat level. They want to increase the max.speed to increase the frequency that's way using 110V,60HZ. In India all climate session will present, there is no more machine fault that's way using 230V,50HZ.

Answer / raviranjan singh

as compared to other countries our Indian electronics and electrical circuits are designed on these parameters. and every country has specified by different frequencies and voltages.

Answer / shiela

High voltage supply makes the appliances run with a smaller
resistance for the same rated current. Since the resistance
is small,losses will be lesser. so India uses 230 V 50 Hz.
