Maybe that Intermatic a good unit. But whenever I see one of those with an
LED, I question its effectiveness. "Surge Protection is functioning when
green LED is on". I say NONSENSE.
Here are some threads I started about the Sycom meter base surge protector
that I have. I think you'll find them ver
Bob,
Good idea to think about CME protection as well as lightening. I
recently had problems at WERU-FM radio station where I am the CE.
At the height of Northern lights, It came in on audio lines and took
down a stereo audio processor at the studio.
At the transmitter site it took dow
The commercial grade protectors are quite a bit more sophisticated than
the few small MOV's network in the small residential units. A look
inside a Joslyn is instructive about what it probably *really* takes to
protect against serious surges. They have means to maintain protection
since MOVs

Bob and all,
Keep in mind, spacing between conductors is typically very small compared to
conductor length. Although there can be exceptions, virtually
Hi Charlie,
Thank you very much for your advice. I agree, and this reminded me of my
forgotten intention to put MOVs (for now) in the meter pole panel. It's
some distance from the house and the wires run underground to the house
panel.
I added a ground rod at that outdoor pole, and it's time to p
I don't doubt that one bit, Tom. But since I have a 30-mile-long 7850 volt
line between my 15 kVA pole pig and the Mt. Vernon substation, I think what
I jerry-rigged was worth doing. (Especially since Ozark Electric in their
infinite wisdom removed all the older spark gaps when they installed the

Well, a few things to keep in mind, Mike:
.Each time an MOV breaks down, Its breakdown voltage decreases a
little, taking its break down voltage closer to the peak voltage of the line
cycles.
.Regarding ground rods - if the ground rods take ligh
Sorry, Mike
I just sent you a reply, but I guess the reflector didn’t like my “bullet
points” and blew out my formatting.

Hi Listers,
Thanks to everyone who contributed to this thread. I've learned a lot and
still have some reading to do. I'd say for now, no more posts needed. Back
to Topband topics.
73 and thanks again, Bob K3UL

It's a long post, but no one complained since there's so much good info in
it. John is a smart fellow.
