Hey, anyone got their HV ticket? or work in the high voltage industry? thinking about steering that way in the industry and could do with some advice cheers
 
Can you afford the training? Will your company pay? Do you need a HV ticket?

Why do you want to go down this road, it’s not fun, it’s downright bloody dangerous!

What experience do you have? 15 years in heavy industry before my company sent me on the HV system management course. Then it’s 3 years and you have to go on the watered down version as a refresher.

Yes I hold a HV ticket and cable jointing to 33KV. A 5-minute job takes 4 hours by the time you’ve done the paperwork and made safe.
 
yeh i was going to pay for it myself , theres a job opportunity maybe coming up at a company and pretty much if i get my HV ticket i can have the job, how dangerous exactly? ive got a lot of experience commercial/light industrial,but nothing the heavy industry such as HV...am i daft for doing it at 25?
 
i know its dangerous, i meant do u actually come within close proximity of energized live conductors.?? i dont have a clue at all never been near 15kv in my llife :/
 
The worse job I can think of is live testing.

You have to open the shutters to expose the live conductors. Then you have the fun of inserting the two foot long probes in to the spout to touch the live conductors. Checking the phasing between two substations is even more fun, you have six live open spouts to sort out.

Think about this, I’ve phased out two feeders, each had 20MVA 33/11KV transformers on each side of the breaker. Get it wrong and there’s no need for a cremation, the undertaker will just sweep you in to a cardboard box!

You don’t get a second chance!

Think about what you’re hoping to do and your experience. Light industrial isn’t anywhere near enough. As I said it took 15 years before I was considered ready. But that was for the HV system management course.
 
It takes a special bread of spark to work on HV. I am not HV authorized and I agree with tony’s point you must have years of experience within heavy industry and you must respect it at all times, One wrong move and it will be the last blue flash you will ever see.

Take a look on YouTube for HV switching.

Dangerous enough for you not to go anywhere near it if you ask a question like that :banghead::banghead:
 
Live testing of MV/HV equipment is normally kept to a minimum. Most testing of these systems are ''dead tests'', on rare occasions as Tony stated you may need to conduct phasing or to confirm live test with probe sticks. Most of the testing to energised systems, come in the form of proving an area which is to be worked on has been de-energised by isolation and the cable cores earthed!! Testing can be just as perilous even on some of the dead testing, such as the Hi Pot tests, which are often conducted at more than twice the nominal voltage...lol!!

Is it dangerous, of course it is, if you don't know what your doing or get careless!! MV/HV systems always command a great deal of respect... One thing you always remember, you don't need to touch these voltages levels, they come out to grab you when you get too close, the higher the voltage the greater the distance it can jump to grab you ...lol!!

Like Tony, I had a lot of intensive training and experience on these distribution systems, from my apprentice days right the way through to the present day. My ''Authorised Person'' training was with both as was then Eastern Electricity Board and the London Electricity Board but i was much younger than Tony at the time. Unlike Tony, i didn't attend jointing training, but have on more than the odd occasion helped certified jointer's, on dead direct buried joints...

Can't tell you how much any of this training costs these days as i have never paid, it's always been company provided. As far as i know, (but it may have changed) You don't need the ''Authorised Person'' status to work on MV/HV, you can also get ''Certified Person'' status, who works under the supervision and control of an Authorised Person...
 
I would argue that yes HV is potentially more dangerous than LV for obvious reasons but following the correct procedures D.I.E.S.I.R. (go on the training and that will make sence) HV work should be even safer than LV.
 
Its not all that bad, you get to wear super sexy suits when you pay with the big stuff ! Just prior to first synch with a 13.8 kV, 40 MVA generator.

Theory is that if anything goes wrong, the flash suit will save your life. Note that even for racking in LV breakers you should be wearing a flash suit, visor and goves as a safety precaution, not than many do.

HeHe, first time I did phasing out I was wearing a tee-shirt and shorts. That was a very long time ago.
Mad, but if you had seen some of the gear we were worked on, you had to be mad! 11KV tee switches that had been in service 60 years, the OCB,s were only 15 years younger. DMO (dependant manual operation) is taboo now but normal when installed.

No it’s not me operating the OCB. It’s a Ferguson Paillin unit, 3.3KV in this case. We used them on 11KV.
