Transformer is a static device to transver power from one
range to another range without any change of freuency.
while generating power they are producing 11kv and then
they used to transmitt upto 400kv through transmission
lines without transformers we cant change the voltage
levels when were are transmitting without any change of
voltage levels losses will be very high higher the voltage
lesser the current IRsquare losses will be less low voltage
transmission and high current means losses will be high
trhats what we are in need of transformers

Answer / meetashok88

Transformer is a device which transmits the energy from one
circuit to another without change frequency.
It can be used for continuous power transmission with
reducing the energy losses.
The power can be step down or step up by transformer for
our need

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???
