Proceedings of the American Institute of Electrical Engineers, 1905
At the last International Electrical Congress, the writer presented a paper on the “Leakage Reactance of Induction Motors,” in which a new leakage element was described, with results of experiment and calculation. A method of calculating the other leakage elements was also outlined. This method, based upon fundamental principles, was checked by a long series of experiments, and while not ...

C. M. Green: I have had quite a little experience and difficulty in making efficiency tests on old arc machines particularly the Brush arc generator. The input and output method, to the best of my knowledge, is the only method b y which the efficiency of these machines can be determined, due to the fact of the large influence which ...
Proceedings of the American Institute of Electrical Engineers, 1909
It is well known that if the wave-shape or the frequency varies from the normal, the loss in a transformer core at normal voltage varies also. It is obvious, however, that the normal loss, that is, the loss with the sine-wave shape and the normal frequency of, say, 60 cycles, can be obtained under the abnormal conditions of wave shape ...
Proceedings of the American Institute of Electrical Engineers, 1911
One of the most important problems confronting a designing engineer is the compromise between the design which, in his opinion, is best but too expensive for competition, and the design which can be built to barely meet guarantees and which can be sold for the lowest possible price. The designing engineer is at times compelled to cater to the idiosyncrasies ...

At the last International Electrical Congress, the writer presented a paper on the “Leakage Reactance of Induction Motors,” in which a new leakage element was described, with results of experiment and calculation. A method of calculating the other leakage elements was also outlined. This method, based upon fundamental principles, was checked by a long series of experiments, and while not new fundamentally, may have some points of novelty in its details. In the present paper this method will be more fully developed and applied to the design of Induction Motors. The leakage elements will be expressed in a novel form and a new method will be employed for the calculation of the power factor. A method of calculating the exciting current will be given with corroborative data. Some new design constants will also be developed.
C. M. Green: I have had quite a little experience and difficulty in making efficiency tests on old arc machines particularly the Brush arc generator. The input and output method, to the best of my knowledge, is the only method b y which the efficiency of these machines can be determined, due to the fact of the large influence which the current in the armature has, at ordinary loads, on the eddy currents in the pole shoes and core loss. Furthermore, the field excitation on the Brush, etc., machines with no current in the armature, and rated volts, runs about 25 per cent of that with normal current and rated volts in the armature, so that you may see that the effect of the armature current upon the field windings is very abnormal. There is absolutely no question about the difficulty of making input and output efficiency tests. It is extremely difficult to get results which will check day in and day out. There is a continual variation of at least 2 or 3 per cent in the efficiency.
It is well known that if the wave-shape or the frequency varies from the normal, the loss in a transformer core at normal voltage varies also. It is obvious, however, that the normal loss, that is, the loss with the sine-wave shape and the normal frequency of, say, 60 cycles, can be obtained under the abnormal conditions of wave shape and frequency by either raising or lowering the voltage. What is needed then, is an indicator which will enable the voltage to be so adjusted that the loss in a transfomer core as measured upon an ordinary wattmeter will be the same as it would be at normal voltage on a circuit having a sine-wave shape of normal frequency.
One of the most important problems confronting a designing engineer is the compromise between the design which, in his opinion, is best but too expensive for competition, and the design which can be built to barely meet guarantees and which can be sold for the lowest possible price. The designing engineer is at times compelled to cater to the idiosyncrasies of certain customers, whose special requirements, experience has proved, are unnecessary and detrimental to good construction, but which will be furnished by competitors who are less conscientious in this respect.
The growth of electrical vehicles (EVs) in the automotive industry has been slower than global research centers expected. However, most forecasts show increased EV adoption in the future due to the quick drop in battery price and the expected increasingly efficient electric charging infrastructures. Surprisingly, reports also predict that EVs will be less expensive to manufacture than a gasoline-fueled internal combustion engine (ICE) by 2030. It is certain that Chinese and U.S. markets will lead the transition from ICEs to EVs.
A. E. Averrett: Regarding the separation of copper losses, there seems to be a tendency on the part of some users to want bar-wound stators on account of the ease of repair. You can make a bar-wound stator with rather deep bars, but if you have a rotor that is bar-wound also and assume that the losses are practically all in the rotor, these will disappear at synchronous speed and you will apparently have a more efficient machine than you really have, if all the losses are taken into consideration. But you can actually get the loss by taking out the rotor and measuring the impedance of the stator alone by wattmeters, which will show up the losses correctly if the tests are made carefully.
The measurements of magnetization, core loss and skin effect of iron at high frequencies described in the following were undertaken partly in order to get data for predetermining the core loss and magnetic densities in high frequency alternators and partly in order to investigate the possible usefulness of iron for transformer construction at high frequencies.
IN laminated-core structures for transformers and rotating machines the need for adequate interlamination resistance becomes more necessary as the core structure increases in size. Where considerable pressures are exerted on the core laminations, a safe value of interlamination resistance must be maintained to prevent the stray losses in the core from becoming excessive. A method for determination of the minimum interlamination resistance required in terms of the core and its operating conditions, for any degree of permissible stray loss, is developed herein, resulting in a simple equation.
It is my intention to bring before the Institute as briefly as may be, the apparent changes in general direction of curves required for predetermining core losses of apparatus, especially transformers, in which silicon steel is used.
The project defines a standard for high-speed (>100 Mbps at the physical layer) communication devices via electric power lines, so-called broadband over power line (BPL) devices. This standard uses transmission frequencies below 100 MHz. It is usable by all classes of BPL devices, including BPL devices used for the first-mile/last-mile connection (<1500 m to the premise) to broadband services as ...
