Explanation
A momentary low voltage is a sag. A synonym would be a dip. Risks to electrical power supply: Blackout: complete loss of electrical power Fault: momentary power outage POWER DEGRADATION Brownout: an intentional reduction of voltage by the power company. Sag/dip: a short period of low voltage Surge: Prolonged rise in voltage Spike: Momentary High Voltage In-rush current: the initial surge of current required by a load before it reaches normal operation. - Transient: line noise or disturbance is superimposed on the supply circuit and can cause fluctuations in electrical power
