Answer Posted / m.b.karthic
transformers are static device....they are used to step up
or step down the voltage in the transmission line....without
transformers the transmission will not be possible because
from the generating station the the voltage must be stepped
up for transmission purpose and after that it has to be
stepped down for domestic and industrial usage

we have require a Motor (1500kW, 6.6kV, 50Hz) which shall operate at 1500rpm during 30min and after it shall run on 500rpm during 15min. The same cycle shall be repetitive during the whole working days. Which method is best and economic to achieve such type of task. VFD, VVFD, Pole changing motor etc.
we all know voltage is a force(emf), and the force always devides if 2 or more than2 loads are there but why does the voltage remains same is parallel, it must devide na ???
