ARE 5162 - Electrical Power Quality for Buildings2 lecture hours 2 lab hours 3 credits
Course Description
This is an advanced course that examines the causes, analysis and mitigation of power quality phenomena found in low and medium voltage systems. Topics covered include voltage sags, surges, interruptions, transients, unbalance, power factor correction, current distortions, and frequency variations. (prereq: ARE 3161) (quarter system prereq: AE 3632)
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Identify various power quality disturbances by their waveform signatures and explain typical techniques for mitigating the problem
