Power Losses in Induction Machines

Transactions of the American Institute of Electrical Engineers, 1934
Losses in induction machines have been subjected to a detailed study by many investigators, but due to the complex nature of some of these losses, particularly several forms of load loss in induction motors, a clear understanding of their nature, has not been available.

Power Line Loss Analysis and Loss Reduction Measures

2019
Line damage refers to the power consumption of power grid lines and equipment, an indicator of the power of enterprise self-digestion. The line loss rate is an important technical and economic indicator of the national assessment of power sector energy consumption level; also, the planning and design of power system comprehensively reflect the level of

Losses in power cycles

International Journal of Mechanical Sciences, 1970
Abstract This paper examines power-producing cycles and evaluates losses incurred in such a way that the analysis applies to cycles as a whole or to individual units involved. This allows the results to be applied to any process where work and/or heat transfer is involved.

Power Losses in Electrolytic Condensers

Transactions of the American Institute of Electrical Engineers, 1932
Electrolytic condensers on a-c. circuits have higher power losses than would be expected from the leakage currents and electrolyte resistances. Likewise, losses change with the applied voltage, with temperature of the cell, with the frequency of the applied voltage, and with external circuit conditions governing current wave shape in such ways that it ...

Power-laws and loss of power-laws in the Tuned Cochlea

IEICE Proceeding Series, 2014
The mammalian cochlea is a sophisticated hearing sensor that uses active amplification to enhance weak sounds. The nonlinearity necessary for this task allows a remarkable dynamic range, yet at the same time it removes the superposition principle, resulting in complex interactions of the incoming frequencies and the generation of new frequencies ...

Research on differential loss benchmark of power loss management in power supply enterprise

2017 China International Electrical and Energy Conference (CIEEC), 2017
Power loss is an important index to evaluate the benefit of the power enterprise. In this paper, a modified power loss benchmark is proposed to calculate the reasonable power loss in the distribution system. First of all, based on grid divider structure, establish the power facility configuration model according to the distribution network load density.

Reactance and stray losses of power transformers

Electrical Engineering, 1934
In this paper are discussed some of the problems of the transformer design engineer in regard to the effect of different winding arrangements, and some of the means employed to predetermine transformer reactance and to keep stray losses at a minimum. A reactance model has been developed to assist the transformer design engineer in checking reactance ...

Losses in high-power bipolar transistors

IEEE Transactions on Power Electronics, 1985
The calculation of power losses in high-power bipolar transistors is examined for several of the commonly encountered types of power circuits. The magnitude of switching and conduction losses is dependent on the type of circuit in which they are used, the type of load, switching frequency, and characteristics of the transistor itself.
