I don't do that with the loops but the fluxgate detectors was considered however, research indicated that they may not have been that good at detecting pedestrians and we ended up with what we have.

We can't put anything sensitive inside the vault, it'll get destroyed with in mins, maybe seconds with electrons bouncing off the walls like they do. As it is, we have problems now with an acid that builds up on everything due to the ozone generation and moisture mixed.

Fly's ??

Interesting. We did the same thing, but with these:

In order to perform accurate ultrasound beam profile tests we had to wait until each bus was at least 1/4 miles down Beethoven Street. I was amazed how heavy and "ground-moving" electric buses can be. This was in Germany where most passengers on these buses are not members of the

Chinese for Fry's? :-)

I used to make heavy duty TV degausing coils. They could affect the image on an old round screen from over 25 feet away. That's why they had 20 foot power cords.

I know a couple of employee's I have in mind, I wouldn't mind using as test subjects.! ;)

No I have not done that but like I said, the feeds come in a long ways from that location plus we have our own transformers. If memory serves we have 12kv lines coming in to our transformer stations. We have 2 out side and 5 transformer vaults in the basement of the main building. But like I said, they are far way, if there was that sort of issue I think we'd see problems in other equipment.

I'll tell you what happen one day though, non related to this thread here, was a general inspection was being done of the 12kV feeds coming in out side from the electric company, something that is done by one of the E1's there. He was out side looking up at a commercial feed coming in and noticed a connecting link to our building was dangling? how could this be? That would mean we're single phasing however, the plant was fully loaded as normal.

It was strange, we started to doubt how our place was wired, because we have another feed coming in. After remembering conversation a I over heard about the third shift electrician making a comment about one area having a voltage issue and he couldn't figure out, it all clicked in and we all seem to agree with that. What was happening was, with all the induction motors we have operating, they were generating the third leg for us..

perhaps a "sun outage"? It typically happens twice a year on dates equidistant from the solstice. Your dish was doing a little microwave astronomy on the nearest star.

Never thought of that at all!

I've got an abandoned dish complete with LNA all provided by Direct TV I could experiment with too. [I asked them to come take it away, but they said they don't do that.]

A crude way of testing for DC on the AC mains is to find a cheap magnetic compass, and put it near the AC lines. It it's stuck perpendicular to the line, at any position, you have DC. If it wanders around, or points in generally the correct direction, there's no DC component. (Note: This doesn't work if the AC cables are run closely parallel to each other). If it happens again, have a magentic compass handy.

Rotating power transfomers. Nice.

Small wok?

Reminds me of a technician of mine. Before he worked for me he worked for GM in Michigan. One morning, at dawn, driving to work in a nasty snowstorm he hit a frost heave hard and lost a hub cap which went sailing off on down the highway.

A mile or so down the road he's waved down by a woman, hysterical, "her windshield had been hit by a flying saucer" ;-) ...Jim Thompson
