Abstract
Harmonic composition of the electric mains in operation of single-phase welding power sources was investigated. It is shown that the welding power sources generate the higher harmonics of current into mains, in particular triplen harmonics, thus deteriorating the quality of electric power. It is recommended to apply the filters of higher harmonics for decreasing the effect of single-phase welding power sources on electric mains.
Keywords: electric mains, single-phase welding power sources, higher harmonics of current and voltage, coefficient of non-linear distortions of current and voltage
