Course Overview

These lessons are excellent for the training of electricians and electronic technicians as well as for the multi-craft training needs of process and manufacturing facilities. The first four lessons in this course cover basic electrical concepts including Ohm’s Law and Kirchhoff’s Law, as well as the use of these laws to determine voltage, current, and resistance in series and parallel circuits.

Module Overview

The tenth lesson in the Electrical Theory for Troubleshooters Course, this lesson discusses Wye and Delta configurations and explains the relationship between phase and line voltages in various connections, and demonstrates the application of the formula that shows this relationship.

Module Objectives

• Describe the relationship between phase and line voltages in a 3-wire wye connection.
• Describe the relationship between phase and line voltages in a 4-wire wye connection.
• Describe the relationship between phase and line currents in a delta connection.
• Calculate power in a 3-phase load.
• Describe the relationship between phase and line voltages in a delta connection.
