Feel Lucky
You missed the point anyway of staying out of the path of least resistance
That is what I was afraid of, climbing a tree with the primary touching it. Full on retarded, full on lunacy. Feel less current? You are insane. Trees touching need a line kill, that is denergized and grounded. Or if you can do it from an insulated bucket truck. Please tell me you are joking around. Anyone else here, for real now, if its touching or even close, (like within 3' of a 12kv line for example) do not climb it.
Clearance you are a hoot
as back then they would laugh you off the job if you refused to do your job, a hot tree is one that has been burning not touching but can be safely trimmed! I have more experience in my left pinky than You will obtain and even though shutting power down would be safer, it will not be done as customers being out of power for days not gonna happen. Getting a bucket on the sides of mountains not possible!
clear again so maybe you can understand miles of line not one little tree or is that too much for you to understand? The term we used was minimum separation means the same I ask you do you know? I know you have a job and understanding of power but limited experience I do hope you stick with the place you work as you could not handle real clearance with a know it all attitude. I hope the best for you and was just trying to get you to understand that being above has a definate advantage if a contact with a limb does occur as it keeps you out of the path of least resistance! Again best wishes on your job and I have no hate of line clearance personal so be safe!Burning not touching, so it has burned away, if under the primary or above it, only inches away. Do you even know the meaning of the phrase "limit of approach"? I think not. Laughed of the job, ok, anyone who asked you to climb those kind of trees would be disciplined and thier company possibly fined, here, anyways. Customers without power for days? Why? I had four line kills on the last contract I was working on, in a month. No big deal, no more than a few hours for the worst one and about 15 minutes for the easiest one. More experience in your left pinky, don't you mean finger, Liberace has pinkies. I wonder about you, but then you are going to heaven if you get cooked, so its all good. For anyone else out there, be smart, educate yourself.
Limits of appraoch are the relationship between the primary and you, the tools you are using and the vegetations proximety to that line. I am not familiar with the voltages you work around, here it ranges from 12 to 500kv, the limits of appraoch for each voltage varies. We use three tables A, B and C. A is for a tested and insulated tool, B is your body, uninsulated tools and vegetation, C is for uncertified workers. On a 12kv line this table is like this A-1', B-3', C-10'. So, if the branches are closer than 3' to the primary, it cannot be climbed, you could however reach over from another tree with a tested pole pruner. As the voltage increases, so do the limits, example, a 60kv line, A-3', B-5', C-10'. What sort of rules or standards do you use in your area?
They are similar however the vegetation is not in the picture you
and conductive tools is the separation factor what we usually would
do is prune it away from the ground first with a rated pruner in them
days they were wooden have since used hotstick with blade mount
better no splinters kind of a peta pruning that many extensions but
safer than climbing and then pruning but that can be done safe also
especially if the winds not blowing. I would some times throw a rope
up to the crown and tie it with bowline and then pull tree and tie off
to create bigger gap but usually not necessary. The wind blows and line
burns limb away usually a foot or better so 3 inch would be hard to
imagine on any distribution line. Lines higher than distribution running
with static instead of ground are a different story transmission are
different as no ground and static build up can cause arc at great distance.
path to ground you still have not fully understood that even though you
just mentioned one way of avoiding it by climbing a different tree to
work from, and yes, I have done that as well there are many safe methods
accomplishing safe line clearance. Staying out of the path of least
resistance is one of the most important things to learn as a clearance tech
as not in the path not shocked.
Is that claire I am sorry but turning off a town for a week1' away aint 3' away and the tree can move closer because of the wind and body wieght. So, no thanks. You keep saying I don't understand, but your misunderstanding or ignorance in regards to how power gets to ground is shocking (ha, ha). Power takes all paths to ground, not just the easiest. "Vegetation is not in the picture" for you, I guess, not for me, seeing how it is conductive and all. You speak with confidence in quite a condescending manner, just what are your qualifications to speak to this subject?
Is that claire I am sorry but turning off a town for a week
was not an option where I worked you keep reading them books boy and
maybe some day no one will have power
Like I said earlier that would not be an optionI said in an earlier post about the contract I just finished working on, four line kills, the longest being a few hours. Your comprehension is on par with your understanding of electrical safety. "We have a billion times more lines", not so good at math either. Does your state have transmission lines that run for over 500 miles?, we do. "The path of least resistance" Good Lord.
Its not good enough to "think", you have to know. Electricity is a strange and powerfull beast, best not mess with it. Some people have been killed by 120 volts, others have survived flash overs from 230 000 volts. Be safe, be smart, follow the rules and you will be o.k. My answer is maybe, not good enough, kind of like, if you are shot in the shoulder with a 9mm, will you survive? Probably you will, care to find out?clearance question if you are on a limb above the limb you are taking
out and the limb under the limb you are on becomes energized do you think you will be shocked?
This was back in the eighties and still some lines that way but I think If shutting the power off and grounding is the way you do clearance you will be safe the problem is no one wants to climb and these lines get skipped and then someone highly trained has to come in and trim but back in early 80s it was skipped due to economy issues they let the lines get bad due to not enough funds jobs were scarce in them days. I would have loved toDon't even speak of burning trees on transmission lines. Miles of burning on distribution? Here it only the rare tree, maybe one in a thousand. Your utility must be incredibly incompetent and criminally negligent for there to be "miles of burning line". I have trimmed and removed burners out of the bucket, or climbed them with a line kill, thats the rules here, thats what I do. This climbing burning trees B.S. makes the arguements over one-handing and one tie in seem pretty small. I would like to hear from a lineman about this, I just know electrical safety in regards to treework.
Well I do agree it is strange but will take the path of least resistanceIts not good enough to "think", you have to know. Electricity is a strange and powerfull beast, best not mess with it. Some people have been killed by 120 volts, others have survived flash overs from 230 000 volts. Be safe, be smart, follow the rules and you will be o.k.

Ok you say I am ignorant on how power gets to ground
and that it takes all paths the thing you are not
getting is the one it takes is going to be the easiest
so if the limb your standing on is energized you are in the
path of least resistance and experiencing indirect contact!
I have been a foreman for line clearance for over twenty years
and yes I still learn the last 13 were as a danger tree expert
for the local coop removing danger trees dead burning and
anything that was problematic. I run a manual crew before that
never me or anyone under me accident numerous safety awards
