Abstract: Disclosed herein are systems for detecting a location of a fault on an electric power transmission line using a state-of-polarization traveling wave in an optical ground wire Various embodiments may also detect a traveling wave on a conductor of the transmission system.

Using the difference in times and the known propagation velocities of the traveling waves, a distance to the fault may be calculated. Arrival time of the state-of-polarization traveling wave may be calculated using electrical signals from photodetectors in an optical channel with polarizing filters at different orientations or reference frames.

Abstract: A multifunction lighthead for mounting to a vehicle includes several groups of LEDs arranged to provide distinct light emission patterns. Each group of LEDs and associated optics are selected and positioned to produce light emission patterns needed to meet lighting standards applicable to the vehicle. Such standards may require wide angle light emission, which is enhanced by supporting groups of LEDs that project away from the vehicle body, enhancing visibility of the lighthead from directions close to a plane defined by the body panel. The projecting support for the LEDs and optics for a wide angle light emission pattern may be employed to support LEDs arranged for ground illumination. Other groups of LEDs in the same lighthead may be arranged with optics to provide area illumination in support of arrest, search, triage or other emergency functions.
