Cause: Overloading, poor ventilation, or insulation degradation can lead to excessive heat. Solution: Regularly monitor load levels, improve cooling mechanisms, and conduct periodic maintenance to check insulation quality.
Cause: Aging, moisture ingress, and electrical stress weaken insulation materials. Solution: Perform routine insulation resistance testing and use proper sealing techniques to prevent moisture penetration.
Cause: Internal winding faults, insulation breakdown, or external disturbances can cause short circuits. Solution: Implement protective relays, conduct periodic testing, and replace damaged windings promptly.
Cause: Accumulation of moisture, dust, or oxidation reduces the effectiveness of insulating oil. Solution: Conduct regular oil testing, filter or replace oil when necessary, and ensure proper sealing to prevent contamination.
Cause: High-voltage stress, manufacturing defects, or aging insulation can lead to localized discharges. Solution: Use partial discharge monitoring systems and replace deteriorated insulation components.
Cause: Contact wear, improper operation, or carbon deposits may cause tap changers to fail. Solution: Regular inspection and cleaning of tap changers, along with timely replacement of worn-out parts.
Cause: Aging, contamination, or mechanical stress can degrade bushings. Solution: Inspect and replace defective bushings, ensuring proper installation and insulation.
Cause: Mechanical shocks or short circuits can shift internal components, causing misalignment. Solution: Secure windings with proper clamping and check for core displacement during maintenance.
Proactive maintenance and timely fault detection are key to ensuring transformer reliability. HANGUANG emphasizes the importance of regular inspections, diagnostic testing, and proper operational practices to enhance transformer performance and lifespan. By addressing these common issues effectively, power systems can remain stable and efficient.
