Video sensing method is applied to the motion study of high voltage switchgears, in which electric contacts are driven in high speed by hydraulic or spring powered mechanism in order to interrupt large current. The presented system combining high speed video and image processing algorithm realized precise measurement of linear or rotational motions of links, levers and cams that are too small to install conventional displacement sensors. Furthermore experimental properties as damping ratio and friction coefficient can be estimated by this method. By implementing those values in the multi-body motion analysis of operating mechanism, numerical simulation of motion shows excellent agreement with the prototype test.
