The Transmission of Electricity is done at 220 KV and not
less than that inorder to reduce the transmission losses
and give the end user a nominal voltage.

Answer / virendra

High the voltage , current is less hence the area of the
conductor is less so also the losses are less.

Answer / pn

coz, to transmit the same power if we go for higher voltage
and lesser current losses will reduce.also somewhere we
have to standardize the voltage level to form a uniform
grid all over the india for easyness & redendancy in the
manufacturing of the equipments.

In a three phase transformer(delta/star connected)when i touch one end of the bulb in any one phase and other end to earth..will the bulb glow or not..if not why?..i'm touching the bulb in star connected side...

I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase, before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???
