Protection for 25 kV Potential Transformer
Protection for 25 kV Potential Transformer
(OP)
What type of protection is required for 25 kV electromagnetic PT used in AC Traction supply lines? Lightning arrester and primary fuse are required or not? What is the practice around the world?

They really don't protect the PT, but will remove it once failed.
