Description

Equivalent circuit for a single phase transformer with NP turns in the primary winding and NS in the secondary, showing:

  • Primary winding resistance RP
  • Primary leakage reactance XP
  • Secondary winding resistance RS, referred to the primary circuit by the turns ratio squared
  • Secondary leakage reactance XS, referred to the primary circuit by the turns ratio squared
  • Equivalent core loss resistance RC and core loss current IC
  • Magnetising reactance XM and magnetising current IM
  • No-load current I0
  • Primary and secondary EMF EP and ES, developed over an ideal transformer
  • Primary and secondary terminal voltages and currents VP, IP, VS and IS
