Sažetak
Natural ester liquids (fluids based on vegetable oils) as non-toxic and fully biodegradable material are alternatives to mineral oils which are environmentaly non-friendly insulating liquids. Natural ester liquids have only recently been used as a dielectric in power transformers so there is not enough experience with this new insulating liquid in service. Oxidation stability laboratory tests enable evaluation of insulation liquid quality and lifetime prediction. In this article the oxidation stability of various natural esters is investigated. The gassing properties of insulating liquids are significant because DGA (dissolved gas analysis) is a diagnostic tool for detecting and evaluating faults in transformer. The gassing behaviour of natural ester and mineral oil under termal stresses is investigated.
