Wago connector under very high current (video)

Thought that was rather impressive! Just bought some of them recently along with the DIN mount hardware for them.

Wonderful video. Clearly no fuse in that circuit! 'Normative', great use of the word.

Impressive connectors.

Wonderful. I can't begin to imagine what 150 amps is like. Certainly enough to blow your socks off!

Nice video, I was actually contemplating getting one of the wago clones (in a type in which I don't think Wago make themselves):



For a lighting project, not any more heh!

[guypettigrew]

Yeh, but you're not going to put 150 amps through it in a lighting job, are you?

Guy

[chris2012]

Heh nah, that's true. Only ~30A, if I was to use a few strips.

When I worked in the labs at Reyrolle many years ago, I used to work with the primary injection rig. It could put out 2000 amps (3 phase) to simulate a fault on a transmission line. The cables we used to connect up the equipment under test were something like 2" diameter, and they used to jump up in the air when the current went on.

[guypettigrew]

Amazing, 2,000 amps. Anyone on here ever worked with this many amps, or perhaps even more!

Guy

Ps Why did you need to test the lines to 2,000 amps?

[Jim]

Ps Why did you need to test the lines to 2,000 amps?

The gear I worked on was protection equipment designed to measure currents and voltages of overhead transmission lines in the electricity grid and operate the circuit breakers to switch off the power automatically (and very quickly - usually within 25 ms). Fault currents can be very high indeed.

The actual transmission line voltage and current are stepped down by transformers before entering the protective gear, so most of our testing was done using what was called 'secondary injection', which was simulating the output of those transformers. You can't exactly simulate the signal that comes out of a current transformer under real fault conditions though, so for type testing we had to use primary injection and use actual current transformers to connect it to the equipment.

Found this video of the type of breakers that I was talking about - the video shows them breaking a normal load current of 150A. Imagine those breaking a fault current 10 times higher!

When I was an apprentice I worked in the shop next door to where they made those; they used to blow a whistle before they tested them and you could here the blast all over the factory.

Incredible! And now you make beer-a much less risky way to spend your time!

you sound just like the bloke who taught my 17th edition regs course,he hadnt experienced 400A 3 phase supply's being used for lighting either
not my work but this is what a 792Kw lighting job looks like

each lamp is 1KW or 4ish amps.

Reyrolle

Remember there industrial plug and sockets,round metal box with a lid held with a bit of chain,plug had a ring that was supposed to screw onto the socket, found almost everywhere industrial (often with the lid missing),then the new fangled ceefoms came along

[chris2012]

Nice, that's a lot of power in those lights!

Out of interest what type of lights are they?

[themadhippy]

par 64's,the workhorse of rock n roll lighting,unfortunately not so popular these days thanks to the emergence of high power leds,but leds cant recreate the quality of the beamage,whatever the salesman tells you.
