Zusammenfassung: | A lightning arrester monitoring device is provided with: a galvanometer (21) for measuring the value of current flowing from a lightning arrester (16) to a vehicle body (19) of a railway vehicle in a circuit (18) between the lightning arrester (16) of the railway vehicle and the vehicle body (19) of the railway vehicle; a data memory (22) that records the current values measured by the galvanometer (21) as history data in time series; and a controller (23) which determines that the arrester (16) has deteriorated and outputs a prescribed deterioration signal if the average value of the current values in a prescribed unit time exceeds a prescribed deterioration threshold value on the basis of the time series change of the history data recorded in the data memory (22). As a result, the deterioration of the arrester (16) provided in the railway vehicle is monitored.
