A Study on the Establishment of Insulation Diagnosis Cycle for High Voltage Rotating Machine

고압회전기 절연진단 주기 설정에 관한 연구

Nondestructive and destructuve insulation tests were performed the high voltage rotating machine in the local thermal power plants. Nondestructive tests include measurements of insulation resistance. polarization index, AC current. tan$\delta$, partial discharge. Destructive tests include measurements of AC hipot and DC hipot. This paper propose to establish the insulation diagnosis cycle for high voltage rotating machine.
