Troubleshooting Guide
Phenomenon | Possible Cause | Emergency Measures |
Abnormal humming | Loose core | Tighten bolts during power outage |
Oil temperature > 85℃ | Overload/poor heat dissipation | Forced air cooling + load reduction |
Bushing flashover | Dirt accumulation | Live cleaning (certification required) |
