The importance on insulation ever increased due to a growing voltage rating of transformers. Within the last decades, although research on the transformer insulation and diagnosis methods has advanced a lot, the insulation of HV transformers remained more or less unchanged. The book is divided into five chapters; the first and second chapters explain the basics of oil insulation, while the third chapter focuses on paper insulation.

This paper describes the application of two relatively new diagnostic techniques for the determination of insulation condition in aged transformers. The techniques are a measurements of interfacial polarization spectra by a DC method and b measurements of molecular weight and its distribution by gel permeation chromatography. Several other electrical properties of the cellulose polymer were also investigated. Samples were obtained from a retired power transformer and they were analysed by the developed techniques. The variation of the results through different locations in a power transformer is discussed in this paper. The possible correlation between different measured properties was investigated and discussed in this paper. Among many other things, the reliability of a power system depends on trouble free transformer operation.

Голос Фонтейна по-прежнему звучал спокойно, деловито: - Можете ли вы его остановить. Джабба тяжко вздохнул и повернулся к экрану. - Не знаю. Все зависит от того, что ударило в голову автору.

 Спокойно, Джабба, - предупредил директор. - Директор, - сказал Джабба, - Энсей Танкадо владеет нашим банком данных. Дайте ему то, чего он требует. Если он хочет, чтобы мир узнал о ТРАНСТЕКСТЕ, позвоните в Си-эн-эн и снимите штанишки. Все равно сейчас ТРАНСТЕКСТ - это всего лишь дырка в земле. Так какая разница.
