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
