The attenuation of the stray current impulse limits the capacitive leakage. The value of the inductance, coupled to the parasitic capacitance of the charge, creates a reactive filter effect. Since the effect is reactive, the impulse energy is not absorbed. The energy is therefore redistributed in time, but since the intensity of the tension is greatly diminished, the coupling through the capacitances is diminished. The apparatus comprises a core which includes 1, 2, 3 or 4 coils. The apparatus is typically a high quality reactance which includes a low reactive value in opposition of the line current (residual mode) and a high reactive value for the circulation of the parallel current (common mode).
