PROBLEM TO BE SOLVED: To provide a device and method which can more accurately detect states and severities of local wear and roughness of a slider of a pantograph.SOLUTION: A camera 43 and an image processing portion 45 photograph downward from above a trolley wire 11 to grasp lateral vibration of the trolley wire 11, and grasp a shape of a sliding surface 21a of a passing slider 21 of a pantograph. A slider local wear determining portion 51 determines whether or not local wear exists in the sliding surface 21a of the slider. Further, the trolley wire vibration determining portion 53 determines whether or not the lateral vibration of the trolley wire 21 exceeds a predetermined degree. With determination results by the slider local wear determining portion 51 and the trolley wire vibration determining portion 53, an overall determining portion 55 overall determines degrees of abnormality of the pantograph.SELECTED DRAWING: Figure 1
