Re: 25 kV PT

Bunnykiller's two 14.4 kV pigs aren't "center tapped
transformers" either, yet he sucessfully overdrives
them in series for 32 kV. My pig had one bushing
grounded on the pole before I "liberated" it with a
chainsaw. Are PT's less robust that pigs? My 25 KV
PT's and my 14.4 kV pig all have BIL's of 125 kV.
