What are the reasons for the low insulation resistance of high voltage motors?

If the insulation resistance of the high-voltage motor is too low, it will affect the normal operation of the high-voltage motor and cause problems such as failure of the supporting equipment.
1. Check that there is no dust and grease on the windings of the high-voltage motor. A small amount of dust and grease will not affect the normal operation of the motor too much. May stop cleaning packaging grease, use absorbent paper to stop waterproofing, and if there is a lot of dust, you can use dry brush to stop cleaning. The windings of high-voltage motors may be submerged in water or moisture. It can stop drying and heat treatment, so, let the winding dry quickly.
2. The insulation of the high-voltage motor is aging first, and the aging degree of the cable must be determined. If it can continue to be used, it needs to be cleaned and repainted, and the treatment is over. If the aging of the insulation wire of the high-voltage motor affects the safe operation of the high-voltage motor, it must be replaced.
