EXTERNAL FAULTS IN POWER TRANSFORMERa. External Short - Circuit of Power TransformerThe short-circuit may occur in two or three phases of electrical power system. The level of fault electric current is always high enough. It depends upon the voltage which has been short-circuited and upon the ...
Transformers are electrical equipment widely used in power systems and electronic circuits. In order to improve the accuracy of power transformer fault diagnosis and condition monitoring, this paper proposes a fault diagnosis method for power transformers based on Random Forests (RFs) and wavelet transfo...
Power Transformers are a vital link in a power system. Well-being of power transformer is very much important to the reliable operation of the power system. Dissolved Gas Analysis (DGA) is one for the effective tool for monitoring the condition of the transformer. To interpret the DGA result...
Power transformers are one of the most expensive components of electrical power plants and the failures of such transformers can result in serious power system issues, so fault diagnosis for power transformer is very important to insure the whole power system run normally. Due to information transmis...

A transformer type superconducting fault current limiter (FCL) for electric power grids was developed utilizing a nonlinear resistor made of the second generation HTS wire. Using of the second generation HTS wire instead of the first one was found to reduce by an order the required amount of sup...
In response to parameter selection seriously affect classification results in SVM, this paper proposes a method using differential evolution optimizes on parameter of kernel function g and penalty parameter c, aiming to getting the SVM machine model for the fault diagnosis of transformer. Firstly, thi...
Partial discharge (PD) measurement and recognition is a significant tool for potential failure diagnosis of a power transformer. This paper proposes the ap... WY Chang,HT Yang - World Scientific and Engineering Academy and Society (WSEAS) 被引量: 14发表: 2008年 Analysis of power transformer dis...
The proposed model combining improved differential evolution(IDE) algorithm with BP algorithm is applied to fault diagnosis of power transformer in the paper. Despite for its simplicity and high-efficiency, differential evolution (DE) algorithm has the problem of parameters difficult to dynamical adjustme...
This paper demonstrates a novel approach for the differential protection of power transformers. This method uses the Wavelet Transform (WT) and the Adaptiv... H Monsef,S Lotfifard - 《Scientia Iranica》 被引量: 4发表: 2008年 Classification and Location of Transformer Winding Deformations using ...
