Apparatus for measuring the distance from the ground of an overhead electric power line

摘要

A portable apparatus (1) for measuring the distance from the ground of an overhead electric power line and the dimension of the conductors or, in general, objects within the measurement region, comprising a generation unit (2) of an infrared laser radiation and a sending and receiving unit (3) of the infrared laser beam, connected to said generation unit (2), and suitable for launching an infrared laser beam towards at least one conductor of said electric power line and intercepting the optical signal scattered by the same conductor.
