D-C Machine Stray-Load-Loss Tests

Transactions of the American Institute of Electrical Engineers, 1937
Two test methods for the determination of stray load losses in d-c machines are described. Application of the loading-back principle permits measurements to a high degree of accuracy. A technique is developed for stabilizing no-load losses so that consistency of results is improved.

Stray load loss tests on induction machines — II

Electrical Engineering, 1936
A new test method is described for the determination of stray load loss in induction machines. By application to given machines, this method is shown to have an exceptionally high degree of accuracy. Values of stray load loss for the same machines are obtained by other recognized methods and results compared.

Stray losses in large synchronous machines

IEEE Transactions on Energy Conversion, 1992
The results of an investigation of the components of stray losses in large salient pole synchronous machines are presented. Stray losses are caused by the magnetic leakage and fringing flux in the rotating machine, and their prediction is subject to uncertainties in the machine design.

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 ...

Stray losses in squirrel-cage induction motors

Proceedings of the Institution of Electrical Engineers, 1964
The correct understanding of the physical origin of stray losses is essential if machines are to be designed with minimum additional losses.

Stray Loss Calculation of HVDC Converter Transformer

IEEE Transactions on Applied Superconductivity, 2012
The development of domestic HVDC transmission system needs the HVDC transformer to perform better. A large amount of higher harmonics will be generated in the load current when the transformer works in a converted way. Due to this, the eddy current field is a nonlinear and non-sinusoidal one.

Stray-Load Losses in Polyphase Induction Maclines

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1959
The total stray-load loss of a polyphase induction machine of the squirrel-cage type is given by the formula: WL = WC + WE + WSL1 + WSL2 + WZ + WB + WK (13) where the several items, except Wc, are given by equations 1, 7, 6, 9, 10, and 12. The sum of WE and Wc can be determined separately from the other losses by measuring the input to the stator when ...

Stray losses in squirrel-cage induction motors

Journal of the Institution of Electrical Engineers, 1963
An article based on a paper with the full title 'Stray losses in squirrel-cage induction motors: validity of the reverse-rotation test method', which is published this month in the Proceedings. The paper has been reserved for reading at a meeting of the Power Division at Savoy Place on a date yet to be arranged in 1964. Dr.

Stray Loss Outside Windings

2020
Stray losses outside windings are a topic that that today is still very interesting and producing a lot of scientific paper every year. The aim of the book is to give a good base for any future work and research on transformer magnetic fields. Topics are presented in the way to teach the concepts and how different solutions work and interact.

Stray loss in solid-rotor induction machines

IEE Proceedings B Electric Power Applications, 1982
The paper presents measurements and calculations of the stray loss in several solid-rotor versions of British Rail's tubular-axle induction motor (TAIM) of 150 kW capacity. The use of a large airgap and of narrow slot openings as means of reducing the loss to manageable levels are investigated, and it is found that the large gap approach is more ...
