we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx
2 4137In VVVF DRIVES VOLTAGE IS ALSO VARY WITH THE FREQUENCY. HOW? WHAT IS THE DIRECT FORMULA RELATING THESE TWO.
2316Q- voltage source of 12v is driving the circuit.if circut draw the current of 0.5A them source voltage will became 11.8v.what is the power dilevered by source when circuit draw 5A current ?
Ecil,
4 6801why is one voltage transformers (instead of three ) installed at the entrence of the incoming line in a substation.
2 3869I try to check the three phase voltage in multimeter, in 125A isolator switch incommer. first i touch R phase, and then i touch Y phase using multimeter, the moment i touched, it blasts and that moment i got blindness. multimeter selector position is correct(750V AC MODE AND RED PROBE WASS IN v AND BLACK PROBE WASS IN COM. MODE. COULD ANYBODY GIVE ANSWER FOR THIS TO AVOID FURTHER ACCIDENTS PLEASE?
2 5460In general, alternating voltage varies between its maximum and minimum values 50 times per cycle. Why don't the circuit element show such fluctuation?

I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
iam using DM 3251 voltmeter(1 percent accuracy)for 11KV system PT ratio is 11KV/110V.can anybody explain what is the max and min voltage deviation.
