modelTrafoMag

Magnetic coupling transformer, 1-phase

Extends from Partials.TrafoMagBase (Base for magnetic coupling transformer, 1-phase).

Information

Stray-impedance and resistance, with non-ideal magnetic coupling, i.e. non-zero magnetisation current and eddy current losses.

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

  r[k] = R[k]
  x[k] = omega_nom*L[k]
  redc = Redc
  xm   = omega_nom*Lm

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]
  redc = Redc/sqrt(R_nom[1]*R_nom[2])
  xm = omega_nom*Lm/sqrt(R_nom[1]*R_nom[2])

with

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