I ran across this paper on dealing with CCVT transients.

They saw a decrease in magnitude of the transients at the test switches after replacing the spark gaps.
Has anyone else...
I have proposed high voltage (230kV) loop feed, leaving the station on one terminal and coming back to the same station on a different terminal.
There are multiple distribution stations tapped on the line.
Traditionally this would have been served radially and protection would be very simple...
