APPARATUS and METHOD FOR STATUS DETERMINATION OF INSULATION DEGRADATION OF ROTATING MACHINE

摘要

The present invention relates to a device for determining the insulation deterioration state of a rotating machine, and by measuring and analyzing the concentration of ozone gas and the wind speed/temperature using a sensor for air discharged from the rotating machine, the discharge amount of the slot discharge is estimated, and the insulation deterioration accordingly. After determining the degree, the administrator is alerted. At this time, the reliability of the ozone concentration value is determined according to the electric field strength value at the measurement location using an electric field strength sensor, and the insulation deterioration of the rotating machine is only below the set electric field strength threshold value. Its purpose is to make you judge.
