 Without electricity there would be no festival. Hello, I'm Paul Jarvis. I'm a site electrician for Powerline. I'm looking after a team of four electricians on this site and we provide power for everybody who wants it and needs it. And some for those who don't. We do try and make this job look as easy as possible but actually it's really quite difficult. Check the waterproof lead on the ground and the job's done. My name's Kev. I'm one of the site electricians. We bring all the generators, the power, the diesel and all the cables to run and power the event for the time that we're here and production are here and of course for the three days of the event itself. Each one of these is 250 KVA generators and we link them together and there's a communications cable between them so that if one of them is struggling the other one picks up the load and it balances an even load and distributes the power into this smaller box which is a sub-distribution which then comes back out of here into here and then we can pipe all the power in separate distributions off from there according to what the requirements are. They're the end user of our electricians at either lights. They use loads of power. They munch it up like nobody's business but they're getting better. As the lights go LED they use less power and the noise boys for some reason their boxes have got smaller but they need more power. So it's about the same amount of power as it always has been but they're just shifting it about differently between the pairs of them. You know they like to compete with each other the noise boys and lampies you'll find that later. How do they plan for the festival? An organised festival like this we get the information ahead we know what power or what distribution is required and we're providing some 63 amp, 3 phase to lighting and 32 amp, 3 phase to sound and that is the main requirement. The stage is very easy to power. Go to the power line We know location for Kev the film crew want to film him again mate. There's an isolator switch inside so I'm just going to switch that on which is basically saving the batteries from draining. The generator is the power station on site. The reason we have two generators on the main stage is if one does fail then the communications cable will send that information to the second generator and that will kick in and carry the load and basically save the show because you don't want both your generators going down so we always use a backup. Here we are, this is it. This is an FG Wilson 200 KVA powered by a Scania power unit which lives inside these great big baffled doors. There it is. It's a hell of a lump. You wouldn't want one of those in your van that wouldn't go very quickly at all. So you've got all this grunt and muscle in here the drive shaft that goes into here which in here you've got three pickups on your alternator so it's pretty much the same as a motor in reverse. So basically it spins around and creates electricity of three points. This is where it gets distributed broken down into smaller usable bits of electricity. So 400 amps a phase there 63 amps a phase there and 16 amps single phases there. There's a way now. You can't really have that doing that while you've got a van playing. It's a bit loud. So shut the doors and it's all alright. But the electrician's job isn't over when the festival starts for them the hard work has just begun. We're backstage here now at Greenman we're in the crew camping area just here next to it we've got four and a half thousand litre bunded tank. That's where we store our diesel. So since we've been here I've already had two diesel deliveries with a big tanker. So that's where we store it but it ain't no good there because my generators are everywhere they're all over the place. So what I basically do is we have one of these this is our fuel bowser it's a thousand litre mobile petrol station if you like it's got a small 12 volt pump on it nozzle counter so we know how much fuel's gone. We're now to the zip round site and fuel up a few little bits and bobs on the perimeter the little sets mainly because they seem to eat more fuel and then when it's quiet first thing in the morning we'll go on to the main entertainment site and fuel the sets there. Some of the generators are causing problems. Yeah lots of them are there that's been a bit funny This one's broken. There's all sorts of things that can cause a fault in generators I mean we suspected that it was Dickey diesel in there from the last job where apparently they got a dirty diesel delivery that can cause the engine to clog and stop. Other things that cause them to go off is if they're overloaded there's all sorts of little things running out. Diesel is a classic for generators stopping. It's the same as all things there's a myriad of problems that it could be but you always have to start first. I love you.
