The power factor is an important indicator of the installations efficiency with light and dark infrared radiators, their individual characteristics. The efficiency of installations depends on used electrical mode. In this paper, the object and subject of research are infrared ceramic lamps for heating, flexible heating tapes for electric heating systems, light infrared radiators and their operation modes powered by complex waveform current. The purpose of the research is the individual parameters of infrared radiators when the amplitude and frequency of the supply voltage are changing and develop recommendations on the choice of effective modes. The authors have solved the following tasks: to develop a method to research the physical models of installations with infrared radiators and to develop recommendations to choose the effective load operating modes based on the results of energy parameters measurements. The authors have obtained the following values of the power factor in the normal and new modes: the ceramic lamp and light radiator–0.97, the flexible heating tape - 0.83. In addition, the authors have proved that the harmonic composition of supply voltage did not deteriorate in the new mode.
