Abstract
A marker for power lines includes a discharge lamp having one of its terminals connected by a cable and a metal jaw to an overhead ground wire. A second cable electrically connects the other terminal to a metallic energy captor which operates by induction in the electric field of the power lines. A sphere made of translucid material and secured to the lamp envelopes the lamp.
