Damage Analysis of High Voltage Motor for Intake Pump

취수 펌프용 고압전동기(6.6 kV, 3,800 kW)의 소손원인 분석

This paper demonstrates the insulation-destruction of high-voltage-motors for intake pump. To analyze the causes of damage in motors, electrical, mechanical and environmental fiery-development were investigated. The insulation-destruction of high-voltage-motors are generally due to the fiery-stress by void where composite materials such as mica/epoxy are used. But this paper shows that electrical and mechanical stresses can be the main reason of the damage, too.
