Is there any rule to select the voltage of motor based on KW rating? What is the rating above which lt motor becomes the HT motor?.
DAE,
1656Whether amorphous core transformer is available in India?.If available then up to what rating of voltage and KVA?.
1685Our transformer capacity is 500kva & voltage ratio is 11kv/433v step down tf.Now i need to know if my input voltage is 10500v and what would be the secondary side voltage i.e output voltage ?
3 4752What is the maximum advisable distance where it is required to interconnect a 500 KVA 480 V 3 ph transformer and the main panel or MCC ignoring the voltage droop affectation, does it is exist any standard about it?
2 2845In case of HV test on medium voltage cables, BS is asking for 4 U0 where as IEC is asking for 3.5 U0. Can any one advise me how this 3.5 times or 4 times U0 is derived?
1651what will be the breaking capacity of MCCB of 1000kVA (6% Impedence) transformer? Voltage being 415V, Power Factor 0.8.
BPC,
2 2911i need to calculate high voltage line power factor daily basics but there is meter reading kwh and kvah while calculating power factor kwh/kvah formula was right. for examble there is point c=13kwh c=1.8 lag c=1.2 lead and c=14.5kvah like that i know that p.f =kwh/kvah but c=1.8lag kvarh and c=1.2lead kvarh points i dont know if u know please reply

What types of I/O have you designed? What were their size? Speed? Configuration? Voltage requirements?
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.
