How to judge the inter-turn short circuit fault of motor stator winding
When a short circuit fault occurs between turns of the motor stator winding, it is generally judged by measuring the DC . However, the DC resistance of the stator winding of a motor with a large capacity is very small, and will be affected by the relationship between instrument accuracy and meas...Read more -
Causes of corona in high-voltage motor windings
1. Causes of corona Corona is generated because an uneven electric field is generated by an uneven conductor. When the voltage rises to a certain value near the electrode with a small curvature radius around the uneven electric field, a discharge will occur due to free air, forming a coron...Read more -
