why transformer ratings in kva?
Answer Posted / vimal raj
transormer is mainly depend on the current an voltage .were
the core an copper losses are due to voltage an current an
this is independent to power factor so power factor is not
alter due this losses for this reason transformer rated in
kva..........

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
