Answer / william lobo

Resin Cast CT and PTs are usually used in indoor
switchgeear 11kv or 6.6kv substations etc. whereas Oil
cooled CTs are used in outdoor substations viz 11kv or 33kv
switchyards.
Difference is that Resin cast are solid cast type. Oil
cooled are those immeresed in Transformer oil and sealed.

In larger capacity CTs where cooling is required then oil
cooled CTs are preferred.

Why single core cable required bonding at double end.
