What is the primary use of a sag scope in transmission lines?

Measuring how far the conductor sags between supports is the key idea. A sag scope is used to determine the vertical sag of overhead transmission lines, so crews can verify that the clearance from the ground, nearby structures, and obstacles remains within design limits under expected conditions (temperature, wind, and load). This ensures safe operation and proper installation tolerances. Other tools like a stopwatch (time), or a device that measures tension (dynamometer) don’t directly measure the line’s sag geometry, which is why the sag scope is the best choice for this purpose.
