RE: Breaker Column Failure Protection for 500kV Live tank Breakers
"On live-tank circuit breakers, the interrupter chamber is arranged in the insulator, which can be either porcelain or of a composite material and is at high potential with the voltage level determining the length of the insulators for the interrupter chamber and the insulator column."
You can Google for "live tank breaker" vs. dead tank breaker design and check on image to see the insulator column.

The concept of using CT on the base of insulator it is common practice for dead-tank breakers design. However for live tank breakers LTB design virtually impossible difficult at best since there is not current flow at the base of the LTB breaker insulator.
If any one have information with LTB with CT as described above post please share that with us
