Continuing the investigation of the post-arc (p.a.) current within low voltage switching process in vacuum, the high modulation frequency of the p.a. current was also taken into account. The constants fitted for the adopted mathematical simplified p.a. model were deduced from the experimental data, considering an equivalent scheme of the quenching chamber in vacuum formed from a capacitance and the electric discharge in a nonlinear environment.
