Information

This example model shows how to use three-phase unbalanced impedances with and without neutral cable.

This model contains two identical inductive impedances with and without neutral cable. The impedances have inputs that allow to change the value of their resistances and inductances externally. The values start to change from their minimum to their maximum values at time t = 0.25 s.

The unbalanced impedance that has the neutral cable sen_N.I[4] is able to measure the current in the neutral. that is the current necessary to satisfy the Kirchoff Current Law (KCL) such that the algebraic sum of the phase current in each impedance is equal to zero.
