inside the regulator is a small, 63:1 transformer (7620 to 120) which will tell the regulator what the output voltage is on the secondary side. you set the operating voltage settings to a high and...
I’m going to discuss the light/power delta bank, with a lighting transformer and two power transformers. Voltage is 120/240/208..
this bank should operate normally with a floating primary neutral....

Use an older analog meter to make the grounds test. A digital meter is too sensitive. It will read the resistance in the wire and show it as the "ghost" voltage. An analog will...
I'm with you guys. I have two concerns about fall restraint; Pole top rescue and people with a fear of heights who can't climb becoming linemen.
I've seen a lot of guys who shouldn't be up on a...
If you have specs to build by, then build it. If you want to use your anchor rod as a ground rod, then go ahead. It's not dangerous, it's just different and has a down-side to it. If you like...
Thanks for the replies, bobbo and rob. I understand where you're coming from. Unfortunately, you're correct in many respects. Just remember that once you're out on the job, you are responsible for...
I'm not sure what you're trying to say here bobbo. Are you that set against company policy? Are you that set against training? I'm not sure I understand where you and rob8210 are coming from....
Holy Cow, what a conversation. Let me add my 2 cents, and the reasons why I have 2 cents to add.
DO NOT bond your neutral to a down-guy or the anchor rod. A down-guy should be isolated from...
Not all of our jib booms were tested for insulation value even though some of the attachments were, so we used a short, 16", stick we called a "pig tail". It had a ring on one end to attach to the...
Sorry, I was in a hurry with the last post and forgot the most important "why". There are three things needed to cause an electric injury...current-path-time. Given enough current, enough time (and...
There's an accepted practice when working energized equipment...for yourself and the equipment. It's called "Isolate and Insulate". Isolate from ground or another potential and insulate from...
I've talked to two guys from Duke and a supplier who knows the crew involved. While not official, this is what I've learned.
The crew was a "training crew" comprised of a journeyman and a couple...
It sounds like you had one those exciting evenings. I agree that something didn't work as planned, or did it?
Your first post asked about 20kv gloves on 138kv. This event involves 34kv which is a...
I've never heard of a voltage building up between the handle and mat (platform). The switching linkage, handles, platforms, ground connections and everything else is built to specifications to...
AB Chance has an excellent video that shows how an equi-potential zone works, and the hazard of working between grounds. It's free by contacting AB Chance.
If you're working between grounds,...
It's not unethical to use accidents by others to get a point across. I begin all my safety meetings with a "Fatality Report", taken off the OSHA web-site. (I'm not a suit, I got my degree in...
Ok kooman here’s what you do. It’s your company’s requirement to wear rubber gloves on the neutral, so when you install the ground end of a grounding jumper on the neutral, that’s what you do. Wear...
Of course there are guys that work primary neutrals without rubber gloves. NEVER OPEN a neutral without jumpering across it first and wearing rubber gloves, but we're talking about touching a...
4kv delta systems are not very common any more at all, but there's still some out there. Be careful if you run into one of them. They're probably so old they're about to fall down. And don't...
I'll be the second guys to admit placing the ground end of the jumper on a neutral with leather gloves. It's the neutral. It's ground potential. It does carry current, but that's why you don't...
"old" linemen working "old" 4kv systems with leather gloves? Yes, it was done and thankfully the practice is over. Most of those systems are also gone too, so don't confuse what they did with what...
Signing a receipt that you received a copy of a safety manual has been around longer than I have. Over 40 years, and well before that. There is no advantage or disadvantage in not signing it. A...
Thanks guys for the comments. I know Canada has used fall restraint for many years now and it's good to know you haven't seen an increase in accidents...contacts or otherwise. That's incouraging. ...
Some conversation going on here. I may as well add my two cents. I've posted these comments in the Safety Forum before, but here goes again.
The Bucksqueeze (BS) and other fall restraint systems...
