Having high power electric cables crossing my garden having read the article in Saturdays Telegraph I would like to know how far they are from my house. Is there a way, without expensive instruments to calculate this? the though of the possibility that my property could be compulsory purchased and demolished saddens me.
A tape measure. Really. Hire shop if you want a long one.
If looking for horizontal distance Are you in an area where google earth has high resolution images? You could use the measure tool (Ctrl+6) to read the distance.
If looking for vertical distance Hmm, trigonometry ? - get a good Maths GCSE student to work it out.
I have read the reply suggesting use of a tape measure .What I'm not sure about is if you want to know the distance from the cable to the nearest part of your house or the distance from the point directly under the cable to the nearest part of your house ...Actually I'm not sure if both things are the same ..lol...might be not much difference if any .
If the latter then a wind-up tape measure like judges at javelin and shot putting use would do . If the former then can't suggest anything although rangefinder cameras had such a device before autofocus became popular . Obviously you'll stay well away from the cables .Electricity jumps remember .

Can you clairfy: what sort of overhead - pylons or poles, what sort of voltage?
Presumably this is connected with the "pylons cause leukemia" think the other week? But what's this about compulsorary purchase - do you have a link?
Cheers

It was published in Scouting for Boys years ago
The way I read the Telegraph article (I went and looked on the website) it implies the horizontal distance. I read that before I made the tape measure suggestion, just in case.
I would guess a hire shop has them.

I read it as distance on the slope, which is a tad more complicated, so my reference to Scouting for Boys.
Link to article in the Telegraph:
Funnily enough, when I first read it, I mentioned it to SWMBO and quoted the same...
Are you allowed to say that nowadays .??
What do you mean by "High Power".
Local circuits are fairly tame. It is the 440,000 volt ones that would worry me.
Don't worry about it - "compulsory purchased and demolished" is not going to happen - Gordon can't afford it! ...and the other two aren't going to be around for much longer:-)

The book is still In Print, so Yes!
Try a 25000:1 OS map or OS get-a-map.

Stand against the house and measure the angle A of the cable above horizontal. Pace the horizontal distance B from the house to the cable.
The distance of the cable from the observation point is B/cosA
You can measure the angle with a board, a couple of nails and a piece of string with a weight on the end:
_______________________ | | | o | | | | | | | | | | | | | | o | | | | | |___________________|___| | | | XXX XXX
Hold the board up so the nails line up with the cable then mark the position of the string against the edge of the board.
OK I will try to elaborate. I wish to measure the shortest distance from the high power cables to my property, so unless I climb the pylon, loop a tape measure onto the lowest wire, then slide it along the cable then measure that off a tape measure will not do. ;-) If it happens, it will be the electrical distribution companies who will have to pay for the compulsory purchase, hence all us electricity consumers who pay, not Gordon Brown, so it could well happen. There seems little doubt that something will be done, of course as we all know it will probably be a fudge. Anyway Central Networks have already agreed to compensate me, it is just a case of negotiating the amount. I am of a mind to postpone any agreement until July by which time the report should be published.
Thanks Rob, for a practical answer, I would try that, only it will give me the distance from the cable at the top of the pylons, not where they pass near my house, also of course, the land between me and the pylon slopes considerably, and there is a bl**dy pool in the way.
