I would like to know what module is needed in tds?ÿ survey pro ?ÿto locate the sag in?ÿan electric line between two poles. I was told that you can locate a pole at each end then the you take measurements that record the vertical angle only. Then when you map it out, it shows the actual sag in the line.
Thank You
I'm running Survey Pro 5.2.1.?ÿ The main menu has a "remote elevation" function that might fit your needs.?ÿ
I have never used it.?ÿ We use a reflectorless TS to record all conductor clearance elevations.
vertical angle offset
take a shot on power pole 1 with a prism pole of known height, record shot, turn to the conductor above that shot, shoot and record.
do the same at the lowest sag
do the same at the other power pole 2
this will give the elevation of the conductors
take and record the ground shots first, this will give the ground elevation, subtract the ground elevation from the conductor elevation thus you have the height above the ground
Use reflectorless and shoot it directly- if no reflectorless sort thru the various offset routines - I think it??s the angle offset- I don??t have it home in front of me right now
This was a trick question, and all of you missed it.?ÿ The real answer:?ÿ you don't locate the sag in an electric line between 2 telephone poles.?ÿ They're telephone poles, so there are no electric lines between them.
Now, if you want to talk about joint utility poles or power poles, well, that's a different matter.

it doesn't say telephone poles.....

The OP has been edited, it did say telephone poles originally.
Depends.
How many chickens are roosting on it? (Arkansas Mississippi specific)
How many tied together tennis shoes are hanging on it? (California Arizona in particular, but New York, and New Jersey too now)
And, what about orange balls, to warn aircraft?
N
I think the function is plane and offset?ÿ
Might be edited- Can??t tell ?ÿ based on the appearance of the site on my iPhone- I can??t check from my laptop, because of the good ole?? http400 bad request bs when I click on the post

If it had been edited after posting, it would have that fact added below the post.
Like this:
I'll chime in here in spite of all the nitpicking and point out when measuring power line sag it's important to note the time observed and local weather?ÿ because the load the line is carrying heats it up (aluminum).?ÿ The power company can dial in the load and accurately estimate the worst case sag condition (hot day, no wind, maximum transmission load).
Don't believe me??ÿ The effect can be observed by the naked eye.?ÿ Observe a line span on a cold winter day with?ÿ wind and low power transmission.?ÿ It's practically bow tight.?ÿ Next summer, observe the same span on a hot day with no wind and maximum power load, it's practically scratching cow's backs.

The trees you're using as a reference in the background have grown since the winter, making the line seem lower. ?ÿ ??ÿ
