This document provides an overview of key topics related to single and three phase transformers, including their construction and operation, the EMF equation, voltage and turns ratios, power equations, and significance of nameplate data items. Learners are directed to read specific chapters in a Jenneson textbook to learn more about transformers, transformer equations, and how to interpret nameplate information.

1. Single and Three Phase
Transformers
Learning Outcome 1

2. Construction and operation of
transformers

3. Read chapter 14.5.1 of Jenneson

4. Read chapter 14.2.1 of Jenneson

5. The EMF equation of a
transformer

6. Therefore the average EMF
induced in each turn = 4 Φ f.
Volts

7. Therefore the r.m.s value of
the induced EMF = 4.44 Φ f.

8. The Voltage Ratio/Turns Ratio
formula

9. The power equation of a
transformer
V1A1 = V2A2

10. The power equation of a
transformer

11. Read chapter 14.3.1 and
14.3.2 of Jenneson

12. State the significance of
nameplate data items

13. State the significance of
nameplate data items

14. State the significance of
nameplate data items
