Tell me the reason of connecting domestic t/f primary in star or delta,and also secondary side.
defination of controlled shunt reactor
Actually I have a doubt on neutral and earth.we use Ac power without taking neutral by connecting to earth,but at that time does it affects on efficiency of any electrical components or no? If yes how?
why the oscillator doent need the ac voltage??how can it produce the ac voltage by applying the dc voltage only??
