Research ArticleOpen accessIn the abstractHot Resistance Estimation for Dry Type Transformer Using Multiple Variable Regression, Multiple Polynomial Regression and Soft Computing TechniquesM. Srinivasan, A. KrishnanProblem statement: This study presents a novel method for the determination of average winding temperature rise of transformers under its predetermined field operating conditions. Rise in the winding temperature was determined from the estimated values of winding resistance during the heat run test conducted as per IEC standard. Approach: The estimation of hot resistance was modeled using Multiple Variable Regression … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 22 Dec 2011 · 7,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Control Technique Applied in Dynamic Voltage Restorer for Voltage Sag MitigationRosli Omar, Nasrudin Abd Rahim, Marizan SulaimanThe Dynamic Voltage Restorer (DVR) was a power electronics device that was able to compensate voltage sags on critical loads dynamically. The DVR consists of VSC, injection transformers, passive filters and energy storage (lead acid battery). By injecting an appropriate voltage, the DVR restores a voltage waveform and ensures constant load voltage. There were so many types of the control … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractMagnetic and Thermal Analysis of Current Transformer in Normal and Abnormal ConditionsM. B.B. Sharifian, M. Farrokhifar, R. Esmaeilzadeh et al.Calculation of Current Transformers (CTs) magnetic and thermal properties are very complex due to the complexity of their construction, different properties of their materials and non-linearity of core B-H curve. Finite Element Methods (FEMs) are very capable and reliable methods for these problems solution, such as Ansys software. In this study Ansys software is applied in analysis of an 800-400/5-5 … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractAging Study and Lifetime Estimation of Transformer Mineral OilMohammad R. MeshkatoddiniProblem statement: Power transformer is the most expensive equipment in electrical network; and the mineral oil has the main roles of insulating and cooling in it. Oil is subjected to the degradation because of the ageing, high temperature and chemical reactions such as the oxidation. Then the oil condition has to be checked regularly and reclaimed or replaced when necessary, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 11,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Parameters of a Power Generating System with Shared LoadRitu Gupta, S.K. Mittal, C.M. BatraThis study presents a model, based on power generating system with shared load. The whole generating system consists of three subsystems viz: subsystem A , subsystem B and subsystem C. The subsystem A consists of one generating unit and one inbuilt transformer. The subsystem B also contains the same units and is connected in parallel to subsystem A.

Research ArticleOpen accessIn the abstractWavelet and ANN Based Relaying for Power Transformer ProtectionS. Sudha, A. Ebenezer JeyakumarThis paper presents an efficient wavelet and neural network (WNN) based algorithm for distinguishing magnetizing inrush currents from internal fault currents in three phase power transformers. The wavelet transform is applied first to decompose the current signals of the power transformer into a series of detailed wavelet components. The values of the detailed coefficients obtained can accurately discriminate between an … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Harmonic Components on Transformer Losses of Sinusoidal Source Supplying Non-Linear LoadsI. Daut, H. S. Syafruddin, Rosnazri Ali et al.An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Transformers are major components in power systems. The increased losses due to harmonic distortion can cause excessive losses and hence abnormal temperature rise. The measurement of iron losses and copper losses of single-phase transformers is important in particular for transformers feeding nonlinear … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 8,398 accessesView PDFCite
