Abstract: This paper describes a mobile test platform with high carrying efficiency, strong adaptability, convenient loading and unloading, and high safety coefficient, which is developed according to the actual working needs of equipment routine sites such as capacitive current transformer (TA) and capacitive voltage transformer (CVT). This paper starts from the drawbacks existing in the traditional operation mode, describes the design scheme of the platform in detail, and at the same time carries out the scheme innovation checking, and finally examines the use effect of the platform from the aspects of safety, economic and social benefits, Then the promotion prospect of the platform is elaborated. Finally, the innovation points and puts forward the improvement plan are summarized.
