itis the ratio of for a given supply voltage the full load
current flowing though the secondary wdg when secondary is
short circuited.
EXAMPLE Given 100v the current is 5 A then 100/5=20
then pERcent=0.02
why this value?
it ios a crucial factor determining the current carrying
capacity of the protection/switch gear of the transformer
N/w
ie suppose rated current is 7 A then switvh gear capacity
=7+0.02(7)=7.15 A
