Outdoor 27.6 kV Bushing CT

Hi,

COuld you advise the preference for a porcelain type or epoxy material for bushing CT application for a 27.6 kV outdoor installation. I tried to search a lot but not much help.

I would appreciate a word.

Thanks

Look at the failure modes, you'll find epoxy much friendlier.

Thanks David.I  have tried to find literature but not much help. I have not been long enough in industry to experience failures and success of these bushings. I can only rely on industry trend, literature and opinion of people like your self.  

Let me rephrase my question:

 Which of these two choices would be a industry trend ?

Your response tells me Epoxy.Then why porcelain is still in lime light?

I would appreciate your input.

Thanks
 

RE: Outdoor 27.6 kV Bushing CT

Maybe I don't follow your question, but a bushing CT doesn't have an insulator. Bushing CTs go around bushings or inside transformers around bushing transitions.

If you're asking about a 25 kV class post-type CT (i.e. not a bushing CT), dry-type CTs dominate that voltage class, primarily based on price advantage over oil-filled units, size, weight, mounting flexibility, safety, etc...
