en Properties of Mineral Insulating Oils in Service قدرت Power پژوهشي Research <p>The infrastructure of the electricity grid and super grid system in the hitherto industrialized world was to a large extent<br> built up in the decades following World War II with a peak in investments around 1960-1980. This means that the<br> flotilla of power transformers is now starting to reach projected lifetime of around 40 years. During the last couple of<br> decades there has also been an ongoing deregulation and privatization of electricity generation and distribution. This<br> has led to higher utilization of existing equipment to deliver an ever increasing demand of power. The demand for<br> planned asset management, investments, reliability and availability of power delivery, has also increased. To ensure that<br> aging equipment is working satisfactory and will do so for yet some time, interest in aging behavior of power<br> equipment has increased. Yet there is precious little basic information openly available on how the insulating materials<br> in transformers behave over longer periods of time. Such information is valuable both from the perspective of<br> transformer maintenance/asset management, and as background information to make informed choices on which type of<br> insulating liquid to employ in new equipment.</p> <p>The infrastructure of the electricity grid and super grid system in the hitherto industrialized world was to a large extent<br> built up in the decades following World War II with a peak in investments around 1960-1980.
