The transformer is a static electric divice. It operates in the principle of electro magnetic induction. it transfers the electricity from the two different closed circuits without any physical contact.
The winding ratio will decide the changing the voltage.
If the primary winding having the less number of winding comparing to secondary winding, that transformer is called step up transformer and vise versa.
If the primary winding and secondary winding are in 1:3 ratio then the voltage will be increased to 3 times of primary side voltage.

if negative of DC supply used and positive is grounded through EGB, and if ELCB used in the system then is it sense the positive volatge and get tripped is it possible?
When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
