Transformer Connections

Learning Objectives

  • Explain how a dual-voltage, single-phase transformer is wound and connected
  • Identify the primary and secondary transformer lead marking
  • Describe the relationship between each phase of three-phase voltage
  • Discuss three-phase, delta-connected line and:
    • Phase voltage
    • Phase current

65 Minutes

When you complete this lesson, you will be able to identify and explain how to make the most common types of connections for single-phase and three-phase transformers.  You will be able to calculate the value of phase voltage and current, as well as line voltage and current.
