Optimal Planning Method of On-load Capacity Regulating Distribution Transformers in Urban Distribution Networks after Electric Energy Replacement Considering Uncertainties

open access: yesEnergies, 2018
Electric energy replacement is the umbrella term for the use of electric energy to replace oil (e.g., electric automobiles), coal (e.g., electric heating), and gas (e.g., electric cooking appliances), which increases the electrical load peak, causing ...

Failure Diagnosis and Root-Cause Analysis of In-Service and Defective Distribution Transformers

open access: yesEnergies, 2021
Diagnostic data of transformers are essential in determining their integrity and to estimate their reliability. Such diagnostic data is not available for distribution transformers as only meagre attempts are made to accumulate this information.

Critical stress of oval foil winding with epoxy coated insulation determined using measured equivalent modulus of elasticity

open access: yesAutomatika, 2020
In the distribution transformers design oval windings are used due to economic advantages. On the other hand, such windings are more susceptible to radial forces in a short circuit.

A Novel Approach to Predict Transformer Temperature Rise under Harmonic Load Current Conditions

open access: yesEnergies, 2022
In South Africa, distribution transformers (DTs) facilitating solar photovoltaic applications represent the highest percentage of total ownership cost investment for independent power producers (IPPs).

On Distributions and Their Transformation to Normality

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1969
Summary Further consideration is given to a family of power transformations discussed by Box and Cox (1964). It is shown that this family of transformations can be useful even in situations where no power transformation can produce normality exactly. The precision of estimation of the transformation parameter is also discussed.

The Distributed Karhunen–Loève Transform [PDF]

open access: yesIEEE Transactions on Information Theory, 2004
The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication between correlated sources, and we investigate a distributed Karhunen-Loeve transform (KLT).
