sag is the difference between the point of support to the lowest point of the conductor.
The plural of sag is sags, not sag's! Sag is caused by the weight of the conductor between its supports, and is (a) unavoidable and (b) necessary to allow for the conductor's expansion and contraction during variations in temperature. When surveyors design a power line, the amount of necessary sag is calculated and built into the design, while ensuring that the clearance between the conductor and the ground remains within safe limits.

SAG
The past tense of sag is sagged.
The sag setting is necessary because it is physically impossible to have a suspended line with no sag. The sag is specified because there has to be a minimum clearance value for the height above ground at the centre of the sag where the cable is at its minimum height.
Sag lasers measure distance.

A power line's 'sag' is the perpendicular distance between the lowest part of a conductor and an imaginary line drawn between the cross arms of two adjacent poles or towers. Sag varies with temperature, increasing as the temperature increases, due to the expansion of the conductor. Sag is necessary to reduce the strain applied to the conductor and its insulators. Regardless of the amount of sag, the lowest point along the conductor must never fall below the clearance height established for the voltage level of the line. The amount of sag is established by the surveyor/draughtsman responsible for profiling the line, and set by the linesmen erecting the line.
You can get a SAG membership card upon appearing in a film, and applying for the card. SAG cards can also be awarded to extras, and once dues are paid, the SAG card will be given.
