WILL THE PERCENTAGE IMPEDENCE FOR A ONAN TRANSFORMEER BE
THE SAME COMPARED TO ONAF TRANSFORMER OF SAME RATING???
Answer Posted / vamsi.n
COOLING SYSTEM OF THE TRAMFORMER IS DEPENDING UPON THE
CAPACITY AND DESIGN OF THE MANUFRATURER THER IS NO
TECHNICAL RELATION BETWEEN PERCENTAGE OF IMPEDENCE AND
COOLING SYSTEM, BUT PHYSICALLY ONAN IS USED FOR LOWER
CAPACITY TRANSFORMERS AND ONAF IS USED FOR HIGHER CAPACITY
TRANSFORMERS IN THAT WAY THE PERCENTAGE WILL DIFFER WITH
EACH OTHER
