The proposed SkySight Technologies Downed Power Line Sensor will detect and alert to the presence of a downed power line and its energized status through a sensor on the power line. In the event of a downed power line, an alert message is sent via wireless network to the utility provider regarding the lines energized status. A concurrent visual onsite indicator flashes to alert first responders and others at the scene to the hazard. The serialized sensor will provide information regarding pole location as well. The study will demonstrate the feasibility of a sensor able to provide real-time line status information that a utility provider can use to plan restoration repairs that return power to the greatest number of people by quickly and accurately dispatching crews to locations where unsafe conditions exist. A Technology Readiness Level TRL 4 is expected at the beginning of the Phase II effort, with a TRL 7 expected at completion. The Phase II effort is focused on refining and updating the design, fabricating prototypes, laboratory testing to meet rigorous standards, and field testing in the working utility grid. Commercial applications include use by large and small utility companies maintaining the estimated 500,000 miles of high voltage transmissions lines in the United States.
