Answer / jayant kumar

as the current to be drawn by the load in case fixed power is being transffred is being proposonal to p/(v cos*).if the voltage level is high he losses and current drawn will be less so impedance drop will be less.so voltage from no load to full load will be nearly same so voltage regulation wiill inproveddd.

in my industry we are using 3 step up transformers for induction heaters..i.e 415/580v and other are 11/440v.in power consumption does a step trnsformer makes any difference compared to step up?? plz explain

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
