RE: [TCML] Single ear piglet

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi Adam,

Yes the lightning killed the pig. And for a moment in time the lights winked
on, followed by the sound of all the breakers being thrown. The utility
folks were out in the hard rain changing the pig and drew a hell of an arc.
An unusable storm for southern Ca. (I'm from the mid-west a long time ago
and miss the shows). I just went out and looked and there are arrestors on
the new pig! The other one was circa 1952. We are at the end of the run and
seriously need new poles!

What I meant, if it is ok with you, is that your schematic was well worth
saving as it is exemplary in construction!

And yes, you have taken many precautions! I'm not trying to be argumentative
either. David's pig is perhaps a little more dangerous than your setup. But
hey, that is the nature of or hobby. I have 3 discharge caps. And as Bert
Hickman put it, "If you wanted to be safe, you wouldn't have bought them."
True enough ;-^)

Are you sure the LV and HV coils were actually shorted together? Did the
utility actually replace their pig? I lost a ton of things in two separate
lightning events, yet the utility's 14.4 kV 25 kVA groundhog was unaffected.
Surges can easily make their way "through" a pig or hog, without necessarily
ruining them. In fact, some of my damage was simply induced into my CAT5
cabling "antenna". I lost every network card (7) and my rack mount hub. That
lightning strike was CLOSE and scared the crap out of me. I was standing on
my front porch enjoying the show.

As to how my wiring affects a LV to HV fault??? Worse case I see is one or
both hot lines are shorted to my RF ground. So? When I liberated my wild
pig, it was fed by a single phase and a ground, with one ear grounded. Or
are you concerned with the HV coming back into my house via the LV windings?
I have a lightning arrester on the HV side, a TVSS on the LV side, filters,
fuses, and finally a breaker. But I don't see how having one side grounded
or not makes any difference. In fact, if the HV and LV windings become
shorted together, I suspect I'll no longer be producing any HV.

And what do you mean by, "I think it should be a saved PDF one horners!"?

I'm not trying to be argumentative; just trying to understand.
