고압전동기의 직입 기동방식에서의 절연특성 개선에 관한 연구

Transient voltage generated at startup included directly in the high-voltage motor, impact damage to the insulation of the motor insulation. In order to improve this, the insulation performance of the insulator will have a significant impact. Presents the cause of damage to the insulation of the motor from overvoltage transients that may not only upright launch large, high voltage motors, and generates various startup operation, the paper, the high voltage generating these I will present a performance improvement plan of insulating material to be protected.
