I've seen regular battery powered tools(dewalt 18v, milwaukee etc..) used on 345kv live. We use Husky battery crimp tools on 13.8kv. I bought a 12v impact for secondary connections since I make...

Gotta test before you put load on. We've had new transformers that were supposed to put out 120/240 that were putting out 160/320. Actually had one stay on line for a few hours before someone...
You don't need them if you're hotsticking either. You may not ever need to wear one, but your employer or utility whose grounds you work on has to do an arc level evaluation of every circuit per...
The messenger is grounded, but it's not a neutral. I have seen it used as a neutral before, but I don't think it was intentional.
Anyway, that's typical Nstar construction. Never trust spacer...
There was a huge abandoned mental health/lobotomy/shock treatment facility where I used to work and there is a really strange looking substation there. The whole place looks like it was transported...
Yes you will most likely be forced to wear one unless the utility that you work for does not have any locations that require it, which is highly unlikely. They can also reduce fault current...
Sorry, made a vague statement and went away for a few days. I meant to say that you cannot bank two three phase banks of different polarities. Like if you wanted to upgrade one bank to a higher...
Just to add to the answers, you can't bank two banks together that have the dead bushing in a different place, even if they are the same voltage. Probably would never see it unless a contractor...
Always good to keep the keep the cut-outs right above the transformer, especially on three phase. Must be fun to move three times to open three doors too... Maybe that's why they are so close to the...

If it's any consolation, one of your safety supervisors went from being the Nstar campus security guard to safety supervisor. Another one become a safety supervisor because he was hurt on the job...
Could be worse.. National Grid had cameras inside the cab facing the driver for a while.
Had same scenario. Mechanics hate them. Regeneration procedure never works and garage supervisors blame us for not knowing how to operate the trucks.
They are good for the environment because...
Where I work it is still allowed to put polymer L.A.'s on by hand no matter the voltage which is obviously stupid. They say that they don't explode so it's ok, which you all know is wrong. I always...
How many times does it need to be explained? If you put one of these online by itself it would get 138.5/240, not 120/240. You get 138.5 volts to from any high side to neutral in the bank when they...
I think they are the best, more comfortable than sneakers. I have three pairs of the 10" waterproof ones. Couple for work and one for home. Definitely blow everything on the lower price end out of...
It wasn't one guy that didn't know how to check the fuse size, it was two of them. Staring at with one eye closed. Showed up with no gear, not even chocks. Stealing out of metal dumpsters because...
Every thread devolves into the same thing no matter what the topic is. This forum is turning to $hit for that reason. Old guys or contractors know everything and are the best workers, that's the...
I think what the original poster is getting at now that I've thought about it for a while is if you change the bank from 240 delta to 138/240 wye, will rotation be the same without checking. That's...
I think you are misunderstanding. 120/208 will always be replaced with 120/208. Nobody is replacing 240 delta with 120/208. What most companies are doing now is replacing straight delta 240 or 480...
Looks like the right hand one is wrong. They are cut on the same angle instead of opposite and one looks longer than the other.
You can keep the same voltage and switch from wye/delta to wye/wye. Like rob says, it's up to the customer how they want to use the service. If there was a ground on it before you change the bank,...
That last paragraph is the best description of investor owned companies that I have ever seen. Should be in the small print under the cool company logo.
I know a guy that destroyed his leg during rodeo practice. Company paid him workers comp. He had no business even climbing, let alone trying to do it quickly. One of the worst I have ever seen. ...
A bad high voltage connection can cause radio static and that sleeve looks pretty bad if you zoom in on it. You would most likely hear some arcing though. It could be buzzing in the trees for a...
