This paper reports the unstable opening and closing speeds with large dispersion encountered by a GIS fast grounding switch during mechanical characteristic test which making testing data results unavailable in accurate reflect whether the product was qualified.By comparing and analyzing the speed results under different conditions,and the reason for the high speed dispersion was then determined to be the inadequacy of testing equipment in fitting the sampling points into a continuous curve.The paper thereby reports further the solution adopted to solve the problem,i.e.,shortening the testing time or using equipment that can fit discrete sampling points into a continuous curve.The proposed method may provide useful inspiration for coping with similar proble ms.
