scope:

Electrical systems will experience electrical events in the form of voltage dips and outages. Depending on the magnitude and duration of these electrical events, electric motors can drop offline. The unexpected loss of an electric motor in a production unit can cause personnel safety issues, environmental issues, and loss profit opportunities (LPO). This Practice provides information which can be used to develop the basic premises on which to implement a voltage dip impact mitigation program to help overcome the adverse effects of production units dropping offline. The voltage dip impact mitigation program addresses the application of both under-voltage ride-through and under-voltage restart capabilities which should be added to the controls of electrical motors.
