Influence of disturbances of arc parameters on the degree of deformation of signals in an electric circuit

The factors influencing waveform distortions at the inputs of selected electric energy receivers were described and their operational effects were indicated. The quantification of these effects was expressed using harmonic content factors. This was done by simulation without taking into account disturbances, with deterministic disturbances and with random disturbances. The electric arc described by the Mayr-Cassie hybrid model was selected as the non-linear load. The dynamic voltage -current characteristics have been included and the values of electrical quantities have been calculated using the THD coefficients.
