A wavelet-based restricted earth-fault power transformer differential protection
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2022-01-20)
In order to enhance power transformer differential protection, especially with respect
to its reliability and speed, several schemes have been proposed in the last years. Faults
inside the transformer protection zone may ...
Analysis of symmetrical components and balanced earth faults in distribution transformers
(Institute of Electrical and Electronics Engineers Inc., 2022-01-01)
The objective of this study is to show the analysis and behavior of symmetrical components and balanced faults in power transformers. Thus, the symmetric component methods solve directly the distribution of voltages and ...
Expert system for the assessment of power transformer insulation condition based on type-2 fuzzy logic systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
An efficient expert system for the power transformer condition assessment is presented in this paper. Through the application of Duval`s triangle and the method of the gas ratios a first assessment of the transformer ...

Power transformers monitoring based on electrical measurements: State of the art
(Institution of Engineering and Technology, 2018-07-10)
Faults diagnosis in power transformers has been traditionally based on the insulation resistance measurement, polarisation index, analysis of dissolved gasses in oil, dissipation/power factor measurement, and partial ...
Sensitivity analysis for overload-relief in transmission lines using an implicitly coupled method (CRIC)
(2006-12-01)
The restructuring of energy markets to provide free access to the networks and the consequent increase of the number of power transactions has been causing congestions in transmission systems. As consequence, the networks ...
