Prediction of the state of deterioration of highvoltage motors by combining on-site, online diagnosis and offline diagnosis

摘要

Offline diagnosis of the stator coils used in highvoltage motors on site has contributed to the early detection of deterioration of many stator coils so far. In predicting the state of deterioration of stator coils used in high-voltage motors, new damage factors can now be addressed by combining online diagnosis and offline diagnosis. In addition, diagnosis can now be conducted at low cost and in a short time.
