Re: is this the correct piggy?

That was kinda hard to follow. So are you saying I was right in my 
assumption that i can get the same performace using a SRSG out of 
this 7kv 15kva pig as a 14kv 15kva pig? And just to make sure, I 
could do this with the same amount of caps only in a different series 
parallel configuration?

Hi Steve,

You are very correct. When I cut the string in two, I forgot that
the "half string" is now twice the capacitance. So when you add the
other half string in parallel, you get the 4X capacitance using the
same number of caps.

I must have been having one of them days. Just forget every thing
I said on that post :-))
