Zusammenfassung:The present invention relates to a technique for determining integrity of a high voltage motor. The technique comprises: a first step of performing a test for an insulation resistance and a polarization index on the high voltage motor; a second step of performing an insulation diagnosis test including alternating current measurement, dielectric tangent measurement, and partial discharge measurement when a test result on the insulation resistance and the polarization index is good; and a third step of drying the high voltage motor when the test result on the insulation resistance and the polarization index is bad. Therefore, the technique for determining integrity of a high voltage motor can improve reliability in integrity determination. 본 발명은 고압전동기의 건전성을 판정하는 기법에 관한으로, 고압전동기에 대하여 절연저항 및 성극지수 시험을 수행하는 제1 단계와, 절연저항 및 성극지수에 대한 시험 결과가 양호한 것으로 판정된 경우, 교류전류 측정, 유전정접 측정 및 부분방전 측정을 포함하는 절연진단 시험을 수행하는 제2 단계와, 절연저항 및 성극지수에 대한 시험 결과가 불량인 것으로 판정된 경우, 고압전동기의 건조를 수행하는 제3 단계를 포함하여, 건전성 판정의 신뢰성을 향상시킬 수 있는 고압전동기의 건전성 판정 기법을 제공한다.
