Hi Folks,

Having moved to a senior post in a renewables installation company, my electrical qualifications and experience cover my responsibilities well, as far as the LV work that is required.

As the company looks at ever bigger projects, HV will inevitably enter the mix and there I will be lacking. We can and will bring in specialist assistance but I would like to understand what I could do to raise my own acumen.

I'm at a bit of a loss where to start. I'm full time employed and it wouldn't be easy to find time to study, but not impossible. I wondered if anyone could offer any advice?

Many thanks in advance, Ian

There are any number of modular courses available ranging from operations and AP through to system design, protection and grading etc etc.

I think first you need to decide at what "level" you need the training and go from there.

We sent a few of our people on a dedicated course for those involved in the renewables sector - all good stuff ranging from legislative overview through to taking control of a system, simple and more complex design and protection and the inevitable G59 arrangements.

Most of the candidates really benefited from it based on what they wanted out of it - we then sent just a selected few on very specific courses based on what they actually wanted out of it on specific projects.



Let the wind blow you, across a big floor.

Thanks for that. I have experience of G59 connections at LV up to 250kW. That includes DNO arrangements and witnessing. It's the jump to 11kV that I'd like to make, to design and specify the equipment for up to 5MW connections.

Having had a good look on the web there are training organisations out there, it would be good to get a recommendation or two from someone who's been there.

Up to a couple of MW your involvement with HV won't be huge. I would suggest a 1 week course run by someone like your local DNO would be sufficient to get you started. These smaller installations will all look the same, usually involving only a length of HV cable, a transformer and at most a single piece of switchgear. A combination of the 1 week course plus on the job training from a hired in contractor for the first 2 / 3 installations would be enough to get you up and running. The thing you really need to worry about is compliance with the Electricity at Work regs - that is the issue that will have you sent to jail if things go wrong. Again you are probably looking at a DNO course plus more extensive on the job training for permits etc until you are comfortable.
Above a couple of MW things might become a bit more complicated, with double infeeds etc requiring you to have a much more thorough understanding of earthing, protection, commissioning etc. I don't think you could really pick this up from training courses alone. It would require fairly extensive on the job training - which you could either write into your contract with the company you bring in, or try and get a secondment elsewhere to pick this up depending on the size of your employer.
