Sags & Swells Symptoms - Distribution Equipment

Voltage sags and swells impact the distribution system very little. Truly severe swells may stress components to the point of failure, but other than that there is seldom disruption or damage.

Problems may arise as the system responds to the load's reaction to the sag or swell. It is possible that if a sag or swell is extreme enough and lasts long enough, the resultant overcurrent could trip breakers or blow fuses.
