How can the lifespan of high voltage transformer bushings be extended?

The lifespan of high voltage transformer bushings can be extended by performing regular maintenance, including visual inspections, oil level checks, and diagnostic tests such as capacitance and power factor measurements. Ensuring the bushing is properly sealed to prevent moisture ingress and conducting periodic oil analysis are also key. Timely repairs, such as replacing worn gaskets and addressing partial discharge issues early, help prevent long-term damage. Using high-quality materials, monitoring operational temperatures, and avoiding overloading also contribute to extending the life of bushings.
