Distribution transformers performance
2005 IEEE Russia Power Tech, 2005This paper present the results of a survey of load, no-load losses and dielectric strength of 123 new and repaired distribution transformers tested by the High Voltage Laboratory of the Federal University of Itajuba within a Research and Development Project in partnership with the AES-SUL - Distribuidora Gaucha de Energia S.A..

Certain Fourier Transforms of Distributions
Canadian Journal of Mathematics, 1951Fourier transforms of distribution functions are frequently studied in the theory of probability. In this connection they are called characteristic functions of probability distributions. It is often of interest to decide whether a given function φ(t) can be the characteristic function of a ...

On Distributional Marchi-Zgrablich Transformation
IMA Journal of Applied Mathematics, 1985The authors extend the classical Marchi-Zgrablich transformations to generalized functions. A testing-function space \(MZ_{m,\nu}(I)\) and its dual are defined. The Marchi-Zgrablich transform of a generalized function \(f\in MZ_{m,\nu}(I)\) is defined as: \[ F(n)=, \] (details of the kernel \(xS_{\nu}\) are omitted) \(n=1,2,3,...;m\geq\), \(\nu\geq -\),

Distribution transformer development
Electronics and Power, 1985The distribution transformer has been with us for almost 100 years and is still evolving. The basic components - core, windings, tank and cooling medium - are all still subject to development, both in terms of refinements to established techniques and from the commercial exploitation of new ...

Managing Distributive Transformers
2018The power companies are aiming for the more cost- effective delivery of high-quality electrical energy. In order to increase the economy and the quality of the electricity supply, it is necessary to connect the substations to the system by means of which remote control and management of substations are carried out.

Lightning Protection of Distribution Transformers
Transactions of the American Institute of Electrical Engineers, 1935Data on the results of lightning protection for distribution transformers on the system of the Georgia Power Company have been compiled, to determine the improvement resulting from changes which have been made, particularly the interconnection of the ground leads of the primary arrester with the transformer secondary neutral.

Transformation of Trichromatic Distribution Curves
Nature, 1947The purpose of this communication is to bring to attention a point which does not seem to be generally realized although it is quite simple to prove. If one of a set of three colour-matching stimuli is altered, the distribution curve for that stimulus is not changed, though one or both of the other two distribution curves is altered.

Magnetic Flux Distribution in Transformers
Transactions of the American Institute of Electrical Engineers, 1922It is customary when discussing magnetic leakage in the transformer to consider the primary and secondary windings as having a counter e. m. f. induced by a flux surrounding the coil and having the core for a part of its path. This leakage flux is frequently represented by closed lines.
