Hi Godfrey, 

In my opinion, lightning arresters make good overvoltage pro- 
tection for pole pigs in piggie powered coil systems, since 
that's what they're designed for by the utility companies in 
the first place. I have a 12 kV rated one that I have used in 
the past with my 14.4 kV pig, but obviously, this is a little 
low for 14.4 kV and the arrester does start clipping the pig's 
output when the variac is turned up to near maximum. Of 
course, it's just doing what it's supposed to do but I can't 
seem to locate a 14 or 16 kV rated one.
