  • Single and Three Phase Transformers Learning Outcome 1
  • Construction and operation of transformers
  • Read chapter 14.5.1 of Jenneson
  • Read chapter 14.2.1 of Jenneson
  • The EMF equation of a transformer
  • Therefore the average EMF induced in each turn = 4 Φ f. Volts
  • Therefore the r.m.s value of the induced EMF = 4.44 Φ f.
  • The Voltage Ratio/Turns Ratio formula
  • The power equation of a transformer V1A1 = V2A2
  • The power equation of a transformer
  • Read chapter 14.3.1 and 14.3.2 of Jenneson
