ELEX 3425 - Electrical Equipment

Electrical and Computer Engineering Part-time Studies Course

School of Energy

To support you and your education, BCIT is adapting applied learning in formats appropriate to the unfolding global situation. All PTS classes are being delivered in an online format unless you are notified otherwise.

Course Details

The focus of this course is on introducing students to three-phase circuits and electrical equipment found in industry. This course builds on circuit analysis from previous courses and gives students the required background for future courses in advanced power system analysis. Topics include: three-phase power analysis, power factor, power quality, line losses, abnormal conditions, protective devices, magnetic circuit fundamentals, transformer operation and analysis, motor operation and analysis, electrical controls (switches and relays), documentation methods and standards for power and control systems such as one-line and ladder diagrams.
