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.
• 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 lines and: – Phase voltage – Phase current
• Discuss three-phase, wye-connected lines and: – Phase voltage – Phase current
• Explain the function of the Y-point in a wye-connected transformer
• Describe an open-delta connection and discuss the amount of current it can provide
• Identify a scenario where a d
