AE 3622 - Building Electrical Systems I

3 lecture hours 2 lab hours 4 credits
Course Description
This electrical specialty course presents advanced design concepts of building low and medium voltage power systems. Students will become familiar with building load flow calculations, power factor correction, per unit fault calculations, arc flash and fault currents, selection and coordination of overcurrent protection between devices, sizing of feeder and branch circuits and electrical code application.  Additional topics include the design of electric service entrances, power company coordination and metering, distribution equipment, emergency generators, motors, underground and campus distribution systems. Case studies are presented thoughout, which reinforce theory and the application of electrical code. Each laboratory session focuses on an individual topic and will be utilized as a collaborative design session to present the implementation of the lecture material. (prereq: AE 3601 )
