Embodiment Construction

[0015] Embodiments of the present invention are described in detail below. In describing embodiments, specific terminology is used for the sake of clarity. There is no intention, however, to limit the invention to the particular terms chosen. While specific exemplary embodiments have been described, it should be understood that this has been done for purposes of illustration only. A person skilled in the relevant art will recognize that other components and structures can be used without departing from the spirit and scope of the invention.

[0016] The present invention provides a method for improving the removal of corrosive components from insulating oils, such as transformer or reactor oils. Corrosive components may contain organic components of sulfur. The present invention works at least in part by converting harmful oil components into easily removable substances. The method is usually performed online. This makes the invention easy to implement, since said steps c...

Abstract

A method for removal of corrosive compounds from insulating oil. The insulating oil is exposed to at least one reducing agent.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application 60 / 754,647, filed December 30,2005. technical field [0003] The present invention relates to the removal of corrosive components from insulating oils, such as those found in transformers. Background technique [0004] Power transformers, distribution transformers and reactors usually include an insulation system consisting of oil and cellulose. These two components have been used for a long time due to their relative cheapness and good performance. The dielectric strength of such an insulation system is very dependent on its insulating properties. [0005] A problem associated with insulating oils used in power transformers, distribution transformers and reactors is the formation of copper sulfide such as cuprous sulfide deposits on the conductors and in the solid insulation in the transformer. Copper sulfide deposition reduces the level of partial discharge (PD) ini...
