In step down transformer (415/200V),mistakenly secondary
side is connected to 415V for some hours, what would be
result of this condition?
Answer Posted / milan
secondary side winding turns is designed for 200 volts. If
we give 415v the secondary side winding turns will not
sustain the voltage . For which insulation and winding both
will damage .If we give 415v to secondary the primary will
get 816.125v
