Conductor marking lights are sometimes used (in conjunction with overhead wire markers) to make overhead power lines more visible. Because power lines are often suspended between widely-spaced masts, they present a particularly grave hazard to low flying aircraft.
Conductor marking lights are sometimes used (in conjunction with overhead wire markers) to make overhead power lines more visible. Because power lines are often suspended between widely-spaced masts, they present a particularly grave hazard to low flying aircraft. A simple and cost-effective solution to this problem is installing marking lights directly on the wires, but there are significant technical difficulties to low-cost power extraction from a distribution system which carries high voltages and wide-range AC current.

Remarks:Example of a magnetically-powered beacon based on a Rogowski coil (similar to a current transformer). This solution is usually intended for medium and high voltage lines up to 440 kV, but inductive coupling devices are able to work on any AC at 50 Hz or 60 Hz, from 15 up to 2000 Amps.
The ideal warning light must be able to power itself while clamped to a single wire of the line. Lights may be powered either from the electric field surrounding the energized wire, or the magnetic field produced by current through the wire. The first approach takes advantage of the high electric potential gradient between conductors, but a strong enough capacitive coupling is requested to allow capacitive extraction of the power required from the warning light. This means that long conductors must be suspended parallel to the line using glass/ceramic isolators: in fact several meters of suspended conductor are generally required, total length being inversely proportional to the line voltage. The second approach is based on Faraday's law of induction involving magnetic flux flowing through a circuit which powers the warning light.
