摘要：
The harmful effect of the electromagnetic field on the electrical personnel from the sources which are rectifier converters used in the converter traction substations is reviewed. The harmonic composition of the rectified current and voltage of rectifier converters is analyzed. It is shown that the rectifier converter is a source of harmonic components of alternating current and voltage, has a spectrum of magnetic and electrical stresses, the harmful effect of which on personnel has not been studied to date. The main analytical relations allowing to estimate the spectrum of higher harmonic components from the rectified current and voltage by means of a calculation are given, the harmonic analysis of currents and voltages at the input and output of the rectifier of traction substations is performed. When comparing theoretical calculations and experimental measurements of magnetic field strengths, it was concluded that the effect of the magnetic and electric fields of the individual harmonics of the rectified current and voltage are harmful.
