Abstract

The application of physical chemistry methods for diagnostic purposes is determined by the nature of chemical processes which are occurring in the insulation of electrical equipment. Three applications of physico-chemical diagnostics are considered: for cables, for capacitors, for transformers and reactors and for bushings. A model of diagnostics for oil-filled cables is proposed. Physico-chemical calculations based on analysis of chromatographic data considerably expand the possibilities of diagnostic control of oil-filled equipment. The results of the analysis of oil for gases and water can be expressed as resource parameters for the equipment
