Inferring low voltage transformer state using only Smart Metering data [PDF]
, 2013 Previous works on Distribution State Estimation (DSE) utilizing Smart Metering (SM) data assume the availability of sufficient measurements from distributed generators and Low Voltage (LV) transformers as well. However, both distributed generators and LV

Transformation of Frequency Distributions [PDF]
Nature, 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]
International 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 ...

Quasi-3D Calculation of Stray Losses in Outer Lamination Stack of Power Transformer Core
IEEE AccessThis paper presents a quasi-3D method for calculating stray losses in the outer lamination stacks of a power transformer core. The method uses multiple 2D FEM models in several steps to capture the 3D nature of the problem.
