Information

Stray-impedance, but ideal magnetic coupling, i.e. zero magnetisation current.

SI-input: values for stray and coupling impedances winding dependent.

  r[k] = R[k]
  x[k] = omega_nom*L[k]

pu-input: values for stray and coupling impedances winding-reduced to primary side.

  r[k] = R[k]/R_nom[k]
  x[k] = omega_nom*L[k]/R_nom[k]

with

  R_nom[k] = V_nom[k]^2/S_nom,  k = 1(primary), 2(secondary)
