X313 Applied Theory III: Polyphase Systems and Controls 120 Hours 6 Credits
This course continues AC theory concepts including resonance, filters, AC power, polyphase systems and transformers. Information on motor controls begins with the principles and applications of DC and AC generators and motors and continues with examples of DC and AC electromechanical controls including schematic symbols, wiring and schematic diagrams, relays and contactors, motor overload devices, time delay circuitry, reduced voltage starting methods, and deceleration methods. The student learns the most effective methods and strategies used to troubleshoot complex electromechanical control systems through hands on laboratory exercises emphasizing electrical safety, electromechanical circuit design and troubleshooting.
Prerequisites: X311 and X312.
