Abstract
A power distribution network monitoring system includes a plurality of measuring instruments that are installed at predetermined positions on power lines constituting a power distribution network and configured to perform electrical measurement of the power lines; a data collection relay configured to receive data related to measurement results from the plurality of measuring instruments; an imaging unit that is disposed near the data collection relay and configured to capture an image including the data collection relay; an abnormality detector configured to use the image captured by the imaging unit to detect an abnormality in the data collection relay; and a storage unit configured to store image data taken by the imaging unit. The image data consists of a single image previously captured by the imaging unit. The abnormality detector compares the latest image captured by the imaging unit and the image data stored by the storage unit and determines whether or not an appearance of the data collection relay changes. If it is determined that there is no change in the appearance of the data collection relay, the image data in the storage unit is updated with the latest image captured by the imaging unit.
