burying high voltage cable

[Engineer54]

Tig,

if you answer what i've asked maybe we can help...

 

[tig]

thankyou 'the ranger' i was beginning to think that i was going to get buried in the right depth hole with appropriate markings and the correct infill

 

[trev]

I don't think there is an actual reg that dictates depth. I think it says something like "Buried at a depth so as to prevent damage and appropriately marked" so obviously you could go deeper through open ground than you could if it was going to be paved over

the terminology MV is a Manufacturers term the distribution and system is still classed as HV



Wait until monday i'll tell you which document to look for I don't have the details at home they're on my desk at work

anyone interested in HV systems apply to the EON engineering academy at Ratcliffe I can't recommend it enough!

Had this arguement before, ...lol!!

EVERY other country i know of, and every company in the industry in the UK, refers to any voltage over 1000v to 36 KV as MV!! It's nothing to do with ''manufacturers terms'' It's an International recognised voltage band!!

You may well have had this "discussion" and yes the Europeans love the MV terminology, But unless something has changed in the last 8 weeks (since i sat my last HV course) we were told to use the terms LV and HV and told exactly where the terminology MV derived from.

Well you were told a load of crap then!! Like our friend netblindpaul, you seem to think we mustn't use the term that every other country in the world uses,(NOT just Europe) we should live in the past and call it HV, just because no-ones bothered to revise a BS paper. Venture outside of your very small world and you'll soon be pulled up, for using the wrong terminology, with a smile of course ...lol!!!

It took me several years myself to get out of calling this voltage band HV, and still sometimes in conversation lapse, but better to start getting use to it, because it won't be that much longer before you will NEED to change too ...lol!!

so are you saying the city and guilds HV operational exams are wrong?

and with all due respect try not be so bloody patronising whats all this "very small world" lark about!

STOP!!! for a minute lads and think about exactly what this "apprentice" is asking.
He says that he is asking a question on behalf of his "employer"!
Now, I'm in no position to judge whether or not the fellow is genuine, but when an "apprentice" asks for information on dealing with cables carrying voltages higher than 1000vac, then I think we have an obligation as "competent" and "responsible" electricians to guide this person away from questions like this, that would be outside of the normal realm and training of any "apprentice" and ask WHO exactly his "employer" is???
This may be the thin end of the wedge and may even put this "apprentice's" life in danger!!!

 

[Engineer54]

Then don't come here, and start telling me about MV/HV!! You've just finished a C&G course and your trying to tell someone that's worked in the MV industry for more years than i care to remember and being an Authorised Person for the majority of those years....

If your talking about terminology aspects in your C&G courses, yes that's exactly what i'm saying, about 15 or so years out of date!!

There are very distinct differences between 33KV and say 66KV as an example, (and further distinct differences, when you reach EHV or SHV) Levels of protection, insulation, separation and transmission, change drastically along with many other aspects. To realistically lump all these voltage bands into one, doesn't make that much sense when you think about it does it?? That is one of the reasons why they are differentiated into meaningful Voltage band definitions, by the rest of the world.

Your very small world consists of your current workplace, go out into the real world of UK and International MV/HV supply and contracting and you'll see what i mean.... And that's NOT being patronising, that's just telling you how it is!!!

I was with one guy for the whole of my apprenticeship. I didn't know at the time but now I realise that some of the questions he would ask and tell me to find the answers to would be unanswerable for me. EG when you do a Ze test on a TN-C-S system and the result is outside the parameters in the regs, apart from contacting the DNO what can you do.
Maybe this lad's mentor is the same as Bill was for me (Even though I hated him at the time hehe)

Patronising and aggressive.

Realise that madmac, and was about too do exactly that, before we once again get side-tracked by unfounded opinions yet again. I did ask some relevant questions of this installation of the OP but afraid no such answers have been forwarded as yet!! Though i doubt any employer would put an apprentices life in danger. Not sure however, how a company can take such a job on, when they have no idea of the strict regulations covering such work!!

 

[Engineer54]

Patronising and aggressive.

Maybe in YOUR opinion, ....But accurate and true!!!

You'll be lucky, it's shut down!

Really how long ago was that ?? So where is this sort of training carried out now Tony??
