Because the Royal Edinburgh Military Tattoo is spread out over a castle we have a wide area power distribution system that starts with a permanent 11kV 1.2MW electrical substation with a backup generator, and then subdivides into several 230/400V 400A feeds that supply different areas of the show.
This video shows a cabin with a dimmer rack, power rack and power distribution modules which all link with 400A single core powerlock tails. We have a lot of cabins like this spread over the whole site and part of the routine maintenance involves thermal scanning during the operation of the show to detect any technical issues. This is all modular power distribution equipment that comes as a flight case which gets tipped up on its end and then the sides removed to reveal all the connectors, protective devices and displays. This equipment tends to get bumped about a lot when it's being shipped between the depots and show locations, so it's useful to monitor it for any signs of loose connections.
We also do a full suite of electrical tests in compliance with BS7671 as the length of run means wwe test it in the style of a permanent install as opposed to a temporary BS7909 install.

    What connectors on top are you doing the patching with? It almost looks like RJ45, but surely that's not mains on that?

    Love the Tattoo videos! My Dad producing the NSIT for many years was a big part of my childhood. So cool to see the tech side of it!! I loved the tattoos, I must admit he did not.

    It's fun seeing the difference between UK and US theatrical distro gear. Occasionally I will work with European equipment, and finding ceeform connectors and those odd value breakers is sometimes a bit of a trick over here. I have a couple of suppliers, but sometimes the parts are a month out because the entire factory closed down for vacation.

    I do wish we had a better alternative to 100A stage pin. They work well and lay flat, but they're awfully sketchy and can be hard to disconnect.

    What happens to the misting unit water if the power does not trip off. Would the water runoff be dangerous to life.

    Surprised they don't use something like CO2 or one of the many Halon-like Halon-replacement mixes to avoid trashing the equipment?

    Clive leave the back door unlocked and I'll sneek in and strike a match near the sensor 😀
