What is this and what is it used for

Henrik:

Now that we know what it is, what they heck was it used for?

Surely not a 5kW coffee mug warmer!

I work at PTB

we have all kind of exstremely parts here 😄 mostly exstemely precise 😉

But since I'm in the acceleration dep., I'll have to ask some fellows, but usually

1. to measure serious currents

2. to calibrate other stuff

 

I just ask myself: How do they generate 23kA DC current without having my desk lightbulb flickering?

 

And THAT is real current plumbing 😄 😄

I was lucky to be able to walk inside one of the JET's flywheel generator which was stopped for maintenance a few years ago. Incredible thing 🙂

More about large dc currents: once i saw a current lead in for a large magnet. The emergency switch was chemical explosives planted on the aluminium current line Smiley Surprised

"Blow the breaker" makes more sense in that context. The "crowbar" for the power supply used Sea-sparrow missile radars  was literally a crowbar sized shunt that would short out the supply if over-voltage conditions were sensed. There is nothing like having your head inside a cabinet, tweaking to tune a klystron and just as you are getting to acceptable an acceptable tune, the crow-bar would trip sound like a gun going off!

Funny how a defective RF gasket in a section of waveguide can make for a very bad day.  High SWR is not good.

or even several bad months when the VSWR alarm goes off almost every day (And, just before evening mess call to boot!) you can miss a lot of dinners trying to find that root cause.

So one evening I was cutting through officer country and found some Ensign DOING PULLUPS on the waveguide!  "Oh I do that every day for Physical Training, unless I'm on Watch!" - He came dangerously close to accidentally falling overboard just about then.

Last night while tending to the orchard I found two of these.

 

What are they and what are they good for?

Aliens in Bens garden 😄

 

Some insects like Gall wasps are able to make plants building their home ....
