Hello
I wish to know about potential transformer used in 34.kV system with secondary 110V. I understand that the secondary voltage will depend on the turn ratio even if the primary voltage goes above 34.5kV. My question is: if the PT is designed for 34.5kV, upto what voltage can it work? Like i read for normal transformers are designed with quite higher voltage as compared to rated (5-10%). What about PT?
