How does temperature control impact transformer bushing performance?

Temperature control is critical for transformer bushing performance because excessive heat can degrade insulation materials, leading to reduced dielectric strength and eventual failure. High temperatures accelerate aging of the oil and insulating components, increasing the risk of partial discharges and cracks. Proper cooling and monitoring of bushing temperatures prevent overheating. Sensors can detect abnormal temperature rises, allowing for early intervention. Managing temperature through efficient cooling systems and avoiding thermal overloading extends the bushing’s operational life and ensures reliable transformer performance.
