FLOW CHARGE EVALUATION DIAGNOSIS METHOD FOR ELECTRICAL EQUIPMENT, AND FLOW CHARGE EVALUATION DIAGNOSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a diagnosis method capable of evaluating flow charge of electrical equipment for both an insulative liquid of a transformer being used at present and a solid insulator.SOLUTION: The present invention relates to a flow charge evaluation diagnosis method for electrical equipment in which a solid insulator and an electrification body are immersed in an insulative liquid. The flow charge evaluation diagnosis method for the electrical equipment is characterized in that the insulative liquid sampled from the electrical equipment and solid insulator particles contained in the insulative liquid are charged and flow charge is evaluated.SELECTED DRAWING: Figure 2
