EE 4480 - Electrical Power Systems Quality

2 lecture hours 2 lab hours 3 credits
Course Description
An advanced course that examines the causes, analysis and mitigation of power quality phenomena found in low, medium and high voltage systems. Topics covered include voltage sags, surges, interruptions, transients, notching, distortions, unbalance, current distortions, and frequency variations. (prereq: EE 3401  or electrical machines course)
