Medium-Size Distribution Transformer Diagnostics

Medium Frequency Transformer Design and Optimization

This paper describes the technical challenges tied to modeling and design optimization of the medium frequency transformer (MFT) for power electronic applications, namely emerging solid state transformers (SSTs). A detailed analysis and modeling of the phenomena governing the MFT electrical behavior as well as limiting the operation and design range is performed. A synthesis of all these models...

The Size Distribution of Superbubbles in the Interstellar Medium

We use the standard, adiabatic shell evolution to predict the size distribution N(R) for populations of SN-driven superbubbles in a uniform ISM. We derive N(R) for simple cases of superbubble creation rate and mechanical luminosity function. We then compare our predictions for N(R) with the largely complete H i hole catalogue for the SMC, with a view toward the global structure of the ISM in th...

Intelligent on-line transformer monitoring, diagnostics, and decision making

The failure of a large power transformer is an area of significant concern since it can result in millions of dollars in costs as well as a possible interruption of power. Therefore, it is desirable to detect the existence of abnormal or anomalous changes in the transformer's internal condition which could indicate an incipient failure. This thesis proposes and tests an anomaly detection scheme...

Review of Important Diagnostics Parameters for Power Transformer

Transformer is one of the most important and costly apparatus in a power system. The reliable and efficient fault free operation of transformer has a decisive role in the availability of electricity supply. In recent years, there has been growing interest in the condition assessment of transformer insulation. In this paper we concerned about the condition monitoring of transformer, benefit of c...
