Splet31. dec. 2011 · Abstract and Figures This paper develops a simplified approach for the calculation of three phase short circuit current in radial low voltage LV networks. This … SpletThe transfer impedance determines SC current along with rated current of primary side. The 10% means the short circuit will present 1/10% or 10x rated current with a secondary short, regardless where the loss is highest. BTW This is also how Hot Spot Temp. Rise tests are conducted using a shorted output but reduced input to match VA capacity.
