Answer / ashish

if you are going for a step up voltage then the voltage
source at lower level (in this case 12v ) has to be very
strong i.e the 12v side should be able to feed the high
current rating of the equipment connected to 230v such as
AC, fridge, water heater , mixer, microwave etc and imagine
if few of the equipments are running at the same time then
amount of power required which the 12v source has to
provide ...its difficult...
and also in such case the insulation level, the conductor
size etc has to be worked out for ECONOMIC point of view ...
its difficult..

Answer / santosh kawade

We can step up AC (alternating current) 12V to 230V by
using 12/230V transformer.

To use the voltage for domestic single phase supply we have
to match domestic appliance rating and 12/230V transformer
and its source rating.

Answer / raj

it is not possible, because like ashish said, it wont
withstand insulation part ,gets oveheated and rbursted,
for each trans former insulation is also a mater with
depends on load and area its gona to use...

Answer / michael

we can step up 12v to 230v but we cant use it for domestic single phase supply . we all know that V1/V2 = I2/I1
the amount of current comes from electronics device will be lower when we use step up again the voltage to 230v. you will attain the 230v but not the current needed by the equipment

Answer / uday

Yes, u r correct mr. Kawade, but transmission will too
complecated, coz as voltage is low then resistance will be
high.

How to calculate voltage drop in copper and aluminium cable? I have laid 240Sq.mm Aluminium cable for the length of 600 Mtrs in 1 Mtrs underground. Normal load is 150A. Transformer is 630KVA, 6.KV/433V. But, I am getting only 395 Volts when load. How to calculate voltage drop and what is the permissible voltge drop for this circuit?

In a company the lines carrying 33KV but the load is below 10000Volts so we know that <11KV we can put 11KV lines but the lines are 33KV,..so how we can step down the voltage to 11KV with out erecting a substation
