Abstract: An example system for monitoring power in a distributed network may include a first surge protector at a first physical location and a second surge protector at a second physical location. The first surge protector may be coupled to a first power source, a first electrical device that receives power from the first surge protector, and a first wireless transmitter. The second surge protector may be coupled to a second power source, a second electrical device that receives power from the second surge protector, and a second wireless transmitter. A receiver at a physical location remote from the first and second physical locations may receive wireless output signals from the first and second surge protectors that indicates conditions of the corresponding surge protector.
