ELECTRICAL TROUBLESHOOTING

Electrical Troubleshooting is a two-week course with formal lectures and student labs. The focus of the course is on the efficient maintenance and repair of electric motor starters, commercial lighting equipment, industrial controls, and sound-powered telephones. IEC & NEMA electrical symbols, one-line drawings, wiring diagrams, schematics, and ladder-logic drawings are used throughout the course. Safe-work procedures, PPE, proper test equipment use, and circuit protection concepts are integrated throughout the course labs and lectures. Motor starting techniques are discussed in detail and range from across-the-line starters to thyristor-based soft-starters. Incandescent, flourescent, and gas-discharged lighting equipment and circuits are studied, as are electromechanical and solid-state industrial control devices. Troubleshooting principles and three-phase power systems are included. Practical lab exercises include wire tracing and construction of field schematics, component identification, component testing, motor and transformer phasing, and troubleshooting of fluorexcent & HID industrial lighting. Significant course time is allocated to hands-on practice using seven different motor-starter/controller configurations. Students will also layout, wire, and troubleshoot a six-station sound-powered telephone system.

ELECTRICITY REFRESHER

This one-week core-level course with lectures and demonstrations is designed to assist students with reviving previously learned knowledge in basic electrical and mathematical skills.  This course covers the subject of basic electricity with an emphasis on industrial and maritime applications.  It is designed as a precursor to more advanced courses for students that have had some formal electrical training.  The course begins with the fundamentals of matter, energy, force, work, electric charge, current, and magnetism.  Basic circuit concepts are then studied, followed by passive electrical component fundamentals.  A brief review of US and European electrical symbols, identification and testing of electrical components/multimeter use, proper interpretation of single-line and schematic drawings.  Single-phase and three-phase power system fundamentals will also be reviewed.

This course is a good predecessor to CMES upper level electrical courses: Electrical Troubleshooting, High Voltage Safety, Instrumentation, Marine Electrical Propulsion, and Programmable Logic Controllers.

This course should not be considered a replacement for our four-week Electricity course.  Those students requiring basic electricity skills will need to take the Electricity course.
