Natural esters are candidate fluids for transformer insulation system. Recently the most common insulation system in power transformers is paper-oil system. Oil generally mean petroleum based insulating fluid. As there are efforts to preserve sustainable development, crude oil products should be eliminated and replaced by natural products, which are easily biodegradable. In past it was shown that...
Natural esters are candidate element of transformer insulation system. Recently most common insulation in power transformers is composed of mineral oil and transformer paper. As there are efforts to preserve sustainable development, crude oil products should be eliminated and replaced by natural products, which are easily biodegradable. In past, it was shown, that natural esters may reach qualities...
Mineral oils, which are currently used as electrical insulation liquids, have due their uneasy biodegradability significantly negative impact on ecology and human health. Thus it is necessary to search for new possible liquids based on vegetable oils or natural esters, which might substitute crude oil products in practical applications. These liquids are easy biodegradable while economically acceptable...
During past decades mineral oils were widely used as electrical insulation liquids. Recently there are efforts to protect the environment against the negative impact caused by possible contamination with crude oil products which leads to a search for new perspective insulating liquids. These new liquids might be natural vegetable oils or natural esters respectively. The properties of all applied electrical...
Mineral oils are traditionally used in transformer insulation systems. As they are uneasily biodegradable, they have negative influence on environment, when transformer failure happens. There are also alternative electrical insulation liquids, which may help in some areas, however their properties may not fulfill the all requirements. This paper is comparing properties of these alternative insulation...
