COMPONENTS OF THE TOTAL POWER LOSSES IN THREE-PHASE ENERGY SUPPLY SYSTEMS WITH SYMMETRIC SINUSOIDAL VOLTAGE SOURCE

Purpose. Three-phase energy supply system with a symmetrical resistive load operates in mode with the highest possible efficiency in a case of zero instantaneous reactive power and the absence of pulsations instantaneous active power. When load parameters are changed, three-phase energy supply syste...
