I get to choose my own fall protection and after much research, I went with the Cynch Lok by DBI/Sala. It's not free climbing, but not a super pain either. There are some decent YouTube videos, if...
This is probably obvious, but remember that parking stands come in both insulated and grounded versions.

Not for nothing, but there are plenty of places a lineman or groundman can get burnt that aren't in the air. Substations, padmounts and especially meter enclosures. I'm not a lineman, but I wear FR...
I'm not sure I understand your comment about the ties. I can assure you that the conductor on the far left is not in a tie on the insulator, but it resting on the metal arm.

Lewy,
Voltage is 13.8 kV. In thinking about it more, is it possible that it is because this is within a mile or two of the boundary between two utility companies. This is in NSTAR territory, but...
The more I look at that photo, I wonder why the cables are not placed on top of the insulator versus being tied to the sides. Would there be a reason for this?

That's what surprised me, especially since this is a quick/easy fix. It's not like I'm suggesting they replace a pole or anything. Which is another story, but my PoCo here in VA has been very...
In an area that I travel to frequently in the Boston area, the condition shown in the photo has been there for over 9 months. I've called the PoCo twice and they obviously don't think it's a...
Amen, but useless without the Sparkys

I assumed he meant this was a high-leg system. Three 240V transformers. One tranny center tapped and grounded. Gives you 120V to ground on A and C phases and 208V to ground on B phase. In the...
Reppy, I don't think the OP is talking about insulated conductor (Hendrix or tree cable), but rather using a substantial insulator to attach the neutral to the pole, versus just a small spool. At...
Just a reminder to not neglect the "smaller" hazards. This story is not related to the electrical industry, but is relevant to those who work with large trucks. I good friend of mine died on Monday...
That is a common misconception. Class 2 gloves are tested at 20 kV, but rated for 17kV. It should say that right on the cuff.
Class 00 - Maximum use voltage of 500 volts AC/proof tested to 2500...
Nice of you to be concerned, but most here know that I am an electrician who does some MV work. I am self employed, so this is my choice. I never work primary alone. I don't have great concern...
I have this hanging inside my bucket at all times. It's under the bucket cover, so it stays out of the weather. Other than that, I work alone most of the time, so a line to the ground would be...

Don't have any details other than the article, but it seems very careless and...
I know working off the back seems the most stable, but in most cases, it is not. It depends on where the lift is attached to the chassis and where the wheels are. For the case with no horizontal...
LNF,
Thanks for the comment. Yes. This is radial. It is a dedicated supply to an experimental system (no residences or businesses). I should have mentioned that. It's also relevant because...
Linemen,
Most of my work in the past has been 4160V with a little 13.2 kV. Anyway, the new system I'm being asked to tackle is 35kV and for obvious reasons, I want to get this right. There is no...
I never thought I would hear a lineman say that about a Sparky, but thanks. I figure it's the least I can do for all the help the Linemen on this forum have provided me.

As one who suffered thru 6 years of Electrical Engineering in college (BS and MS) before I found my calling, I can try. The right-hand rule is generally used as a guide to correlate the direction of...
Thanks for the info. I was probably mistaken when I said a cable company. I didn't want to get into specific names, but the company in question provides telephone, internet and TV services (don't...
Have a pole here that is on customer's property (house is about 600' from the road). Pole has a VERY old transformer and the power service for this one house. Reported to the PoCo back in July that...
Got it. I thought it might be an area measurement. Here it is in circular mils or MCM for 1,000 circular mils. Circular mil is the area of a circle with a diameter of 1 mil. It keeps PI out of...
