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

This is the final lesson in the Electrical Theory for Troubleshooters Course. This lesson builds on the information presented in the lesson, Introduction to Transformers. How to determine primary current and voltage, secondary current and voltage, and load is taught. The function of various transformers is also explained.

Module Objectives

    Given the secondary voltage and load, determine the primary current.

  • Given the primary voltage and load, determine the secondary current.
  • Given the turns ratio and voltage and current from either the primary or secondary, determine the power.
  • Given power and primary voltage, determine primary current.
  • Given primary voltage, determine secondary voltage in a 3-phase transformer.
  • Describe the configuration of a 3-phase transformer.
  • State some applications and maintenance precautions for a 3-phase transformer.
  • Explain the functions and uses of multi-tap transformer and autotransformers.
