No abnormal conditions are observed from Corona Discharge Test. Dielectric strength of stator coil is over 2E+1,000 (V).

The fixed conditions of stator coil have no problem.

Dielectric strength of stator coil is over 2E+1,000 (V). However there are void in insulating layer, deterioration of corona protection layer, and corona between different passes are observed. More frequently test is recommended for attention.

Peeling of insulation layer from electric coil and/or void in insulating layer are concerned.

More frequently test is recommended for observation.

Deterioration of corona protection layer, increasing of corona between different passes, or down of fixed strength for stator are concerned. Overhaul and necessary repairs are required.

Deterioration of insulation on stator coil is confirmed. Replacement is required.

Maximum Quantity of Discharge (Qmax) is reducing in association with temperature increase
