Impedance Calculation 2021 — Loop

( I_f = 230 / 1.796 \approx 128 , A ).

Earth loop impedance, often denoted as Zs, represents the total resistance of the path through which fault current flows when an insulation failure occurs. This path starts at the point of the fault, travels through the earth protective conductor, reaches the transformer star point, and returns through the phase conductor. loop impedance calculation

$$Z_{loop} = Z_{conductor} + Z_{transformer} + Z_{other\ equipment}$$ ( I_f = 230 / 1
