| Abstract: | Over-range hydrogen on oil-immersed current transformer would cause equipment failure which will endanger the safe operation of power grid. The paper takes a failure investigation of oil immersed current transformer as example. Analysis about the reason of over-range hydrogen on oil-immersed current transformer based on oil chromatographic tests and dielectric loss tests. Some treatment methods to prevent similar accident from happening are provided. |
