Efficiency Improvement of an Electric-Grid Transformer Using the Diamagnetism Characteristics of a Bulk Superconductor

open access: yesEnergies, 2022
An innovative method to improve the efficiency of a single-phase electric-grid 125 kVA, 50 Hz shell type and distribution transformer is presented. The diamagnetism characteristic of a bulk high-temperature superconductor (HTS), designed in a specific ...

Transformation of Frequency Distributions [PDF]

open access: yesNature, 1948
FREQUENCY distributions of numbers of eggs, insects, spores, or other biological entities are descriptive of discrete variation, and can never be represented exactly by a normal distribution or by any other distribution of a continuous variate. Nevertheless, when the number of observations and the range of variation is large, such distributions may ...

The stieltjes transform of distributions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
In the present work, two complex inversion formulas of Byrne and Love for generalized Stieltjes transformation are shown to be valid for a class of distributions. This is accomplished by transfering the complex inversion formulas on the testing function space of a class of distributions and then showing that the limiting process in the resulting ...

Experimental validation of using frequency response analysis method in measuring interwinding capacitance of power transformers

open access: yesEngineering Reports, 2019
The interwinding capacitance of transformers describes the diagnostic status of winding‐insulation and its geometry. Naturally, there is a constant drive in improvising the existing methods and to attain accurate information while measuring interwinding ...
