Abstract: Lower in Power Factor of electrical equipments will draws high current from supply power. The effect of this is affected by impedance of electrical equipment. Therefore, the main consideration of this study is how impedance of electrical equipment affects the power factor of electrical loads, and then distributed power as the whole. This study is important to verify the right action to increase low power factor effectively for electrical energy efficiency concern.

But the efficiency of industrial electrical units can also be assessed by other criteria. In particular, using the vibration monitoring method, it is possible to increase the energy efficiency of an electric motor by eliminating faults. Damage to electric motors (imbalance, bearing damage, shaft wear) leads to an increase in electrical losses, and, consequently, to a decrease in the energy efficiency of the motors.THE PURPOSE.

The use of not one, but two or more different physical properties of the separated ore components during radiometric beneficiation opens up additional possibilities in increasing the selectivity of this process and expanding the scope of its application. It is proposed to reduce the energy intensity of crus

Abstract:

The electrical equipment operation is cost-effective and reliable when operating parameters of the electrical network correspond to the rated data of the equipment. The real operation conditions, however, differ from those required for electrical equipment, which negatively affects its efficiency. The non-sinusoidal conditions in electrical networks are currently very common. The paper provides an overview of the characteristics obtained from an analysis of publications, which are used to evaluate the effect of the non-sinusoidal conditions on power transformers.

The availability of significant amount of solar energy in Sahelian countries can make the application of water pumping through photovoltaic generators very attractive solution for irrigation of agricultural land and drinking water supply to remote sites. This paper discusses the effect of harmonic currents on the energy efficiency of electromechanical equipment in a water pumping system. The electricity grid is already assumed to pollute upstream by non-linear loads in which the current is not proportional to the voltage applied. These harmonics do not produce active or reactive power, only lo
