What are voltage sags, dips, swells and transients? | Fluke

Electrical and electronic equipment is rated for operation at a specific voltage. Voltage dips, swells and transients can cause trouble with industrial controls as well as equipment such as computers. Surges are generally more damaging to equipment than dips, but both can harm industrial equipment and cause outages, failures and other power quality problems.

Sag in transmission lines

Keeping the desired sag in overhead power lines is an important consideration. If the amount of sag is very low, the conductor is exposed to a higher mechanical tension which may break the conductor. Whereas, if the amount of sag is very high, the conductor may swing at higher amplitudes due to the wind and may contact with alongside conductors.

Overhead Line Sag Tension with Calculation and Example

The following are some of the effects of ice and wind on sag: When the wind blows at a specific force on the conductor and ice forms around it, the weight per unit length of the conductor changes. There is alternation of the conductor''s self-weight per unit length horizontally in the direction of the airflow by the wind force.
