Abstract

This invention provides a method for diagnosing an insulation member of an electric apparatus, the method being capable of measuring the insulation without being affected by external environment at the time of measuring, and the obtained diagnosis data can be corrected to meet any conditions of the external environment. The proposed method includes the steps of: selecting the diagnosis items and a plurality of the measurement items having a strong relation with the diagnosis items, showing the relation between the diagnosis items and the measurement items on a relation graph based on the measurement data of the diagnosis items and the measurement items obtained from a sample of the insulation member (S11), preparing a characteristic graph or a characteristic formula representing the relations between the diagnosis items and the factors of external environment (S12), designating an index to represent the measured diagnosis data of each measurement item with respect to the object measurement insulation member being diagnosed using an MT method, and reading the values of corresponding diagnosis items from the relation graph prepared beforehand (S13), and showing the reactions between the values read in the above step and the factors of the external environment in the form of a characteristic curve using the characteristic graph or the characteristic formula, and obtaining the correction values of the diagnosis items in which the effects of the factors of external environment have been considered.
