How I want to know how the B-H charateristic of cores used in transformer or any other device changes with a period of time. I mean to ask the effect of climate, period of usage of transformer, effect of under load and overload on this B-H curve. Whether the curve for new core will be same as B-H curve of an old curve of same material? Please give me details if possible?
