Hello, Thanks for the reply This motor was new and installed one year ago. We were doing its slip ring chamber's inspection, cleaning fortnightly, nothing was found abnormal anytime. Please find attached sketch where i have marked faults. Inter-turn fault caused these links shorted with Ground/shaft or vice versa? Can you share any document on such kind of faults in slip ring motors rotors AttachmentFaults Location.docx (213 Downloads) |

Hello saqib2311, Ground fault occurs due to failuer of insulation material. Inter turrn short is because of overheating/overloading winding. Overheating is the sommon cause which leads winding interturn short & simulteneously detoriation of insulation which over period leads to ground faults. This information is shared based on practical/technical information. I do not have any documentry evidence. HTH. |
