Abstract

Recently, the insulation breakdown accident has been experienced at 6.6kV inverter driving motor. That brought about the reliability degradation of motor driving system.. We need to find the solution with system engineering level. The objectives of this study are developing the appropriate filter for the drive to protect the motor and the Insulation system of motor which Is driven by inverter. We clarify the cause of the deterioration of the inverter driving motor through the analysis of Insulation breakdown accidents.
