Bushing failure can be caused by insulation degradation due to moisture ingress, oil leakage, thermal stress, or electrical overloading. Contaminants in the oil, mechanical damage from environmental factors like wind or seismic activity, and aging materials also contribute. Poor maintenance, improper installation, or failure to detect partial discharges early can lead to catastrophic bushing failures.
