Abstract :
In This work a power quality (PQ) problem in an industrial plant is analyzed and its possible solutions explored, specifically regarding voltage sags. It is analyzed a plant\´s electrical system sensitivity regarding voltage sags, how does the magnitude depression and its duration affect the performance of the electrical loads (mainly induction motors). Several proposals are discussed and explored for voltage sag mitigation and their feasibility for the plant\´s PQ problem. Finally, settings of the voltage sag mitigation equipment (timer or "latching" relay) are made analyzing voltage recovery times after voltage sag has occurred.
