Measure the length of a wire, electrically

Catwell over 13 years ago

This is probably old news, but is there a way to measure the length of a wire electrically?

This is a wire strung along the inside of a warehouse wall.

I could have access to either end.

I am picturing some sort of ping time test done at one end.

Let me know if you have any ideas.

Hi Cabe, You could measure the resistance, but you would need access to both ends of the wire. If you have a good building ground and regulated power supply, you could measure the voltage drop from one…

Maybe you could extrapolate the fact that you can strike a wire rope with a bar and time how long the mechanical flick or pulse takes to return. This would only work if the wire is not supported between each end as you do not specify.
