METHOD FOR ANALYZING INSULATION STATE OF ELECTRIC APPLIANCE FOR IMPROVING ANALYSIS PRECISION WITHOUT BEING INFLUENCED FROM EXTERNAL ENVIRONMENT

摘要

PURPOSE: A method for analyzing an insulation state of an electric appliance is provided to improve analysis precision by totally analyzing the defect of the electric appliance without being influenced from external environment. CONSTITUTION: After selecting analysis items and measurement items having storing relationship to the analysis items, measurement data of the analysis items are obtained. Then, the measurement data are displayed as an index and a relationship between the index and the measurement data of analysis items is displayed(S11). A characteristic view or a characteristic equation is prepared in order to display the relationship between the analysis items and the external environment(S12). Then, the value of the analysis items is analyzed based on the relationship between the index and the measurement data of analysis items(S13). After obtaining a correction value of the analysis items(S14), a life span of an electric appliance is measured(S15).
