Abstract:
This disclosure describes techniques implemented at least in part by a fuse-monitoring device to detect when a fuse cutout in an electric power system opens to disconnect a device and/or a load from a power line, and provides an indication of a location of the opened fuse cutout to a utility provider. The fuse-monitoring device may be attached to a fuse holder of the fuse cutout, and may include a movement sensor that detects when the fuse holder swings open due to its fuse melting, or blowing. The fuse-monitoring device may send a notification to the utility provider indicating that the fuse holder has swung open. The fuse-monitoring device may include a GPS sensor to determine the location of the fuse cutout, and may also notify the utility provider of the location of the fuse cutout so a line crew can quickly locate the fuse cutout that requires maintenance.
