Answer / parimelazhagan

current also increases

Answer / adithye

When there is a load connected and if the voltage increases current will decrease to balance power P=VI

Answer / vani

as per ohms law,
current directly proportional to voltage across the conductor and inversely proportional to resistance.so as voltage increases then current also increases.i hope this is correct in my way of thinking.

Answer / masang

as we know
V/I=R
so if R remains constant then with increase of voltage,current decreases.

say a transformer is designed for 33/11kv step down with ratio 0.33 for load 1 mva. if am giving 11kv as a input that same transformer what will happen to its o/p voltage. and whether it can be operated for 500kva

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses?  the second question is-generation is depends on LV winding? or LV winding design for generation voltage?

Hi, I'm running plastic reprocessing company where all motors are running only in delta. Due to that when I use start my 30 hp motor my transformer gets fuse. Where it happens two times a day. I gt a suggestion from a person about Automatic Power Factor Controller APFC. Is it useful for my problem??? Or is der any other way for solving this problem?? Upgrading the transformer is difficult. Pls give Me ur suggestion. Waiting for ur reply.
