ARE 3161 - Design of Power Systems3 lecture hours 0 lab hours 3 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 throughout, which reinforce theory and the application of electrical code. (prereq: ARE 3101 ) (quarter system prereq: AE 3601) Course Learning Outcomes Upon successful completion of this course, the student will be able to:
- Explain distribution system configurations such as radial and loop and their selection, motor operations and controls
- Describe system grounding and ground fault protection
- Calculate AC current, voltage, impedance and power using complex numbers
- Prepare ohmic and per unit short circuit calculations by hand
- Prepare system studies using power system analysis software
- Prepare service and feeder calculations including demand factors
- Formulate conduit and conductor size and grounding for various load types
- Devise building voltages and proper voltage system selection according to facility use and size
- Devise overcurrent protection including molded case, insulated case, and power circuit breakers and fuses
- Design electrical power distribution for a large commercial building or campus center
- Evaluate major electrical equipment for a building service including switchgear, motor control centers, switchboards, transformers, emergency systems and panelboards
