TRANSFORMER REMNANT LIFE ESTIMATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a transformer remnant life estimation system quantitatively evaluating the level of degradation of insulation due to composite deterioration of a dry or mold transformer, and statistically estimating remanent life thereof.;SOLUTION: This transformer remnant life estimation system is provided with: a storage means respectively storing gradients on a characteristic basis and on a reliability basis obtained by executing regression analysis of aging data of an electric apparatus used in the air, magnification of a value at second reliability to a value at first reliability on a characteristic basis, and remark documents; a data input means inputting data of the transformer; a characteristic value estimation means calculating the number of years elapsed from input manufacturing date and investigation date to estimate transition of the characteristic value at the first reliability and the second reliability after the elapsed years by using the input characteristic value; a remanent life estimation means estimating the remanent life required until the characteristic values respectively estimated at the first reliability and the second reliability reach predetermined defective level values; and a remark document retrieval means retrieving the remark document based on the estimated remanent life.;COPYRIGHT: (C)2009,JPO&INPIT
