Intern Profil

Overhead line maintenance operators.

Required

Employees required to carry out topographical surveys for setting up and checking the location of overhead lines,

Mastery of the CELESTE tool.

Needed stuff

PPE, a PC with the CELESTE tool installed and something to write with.

/ Content

• A reminder of the technology of the associated equipment and materials, distance and height measurements (hooking and obstacle) and the verification of an overhead line cable parameter,
• Distance measurement using the "base range",
• Use of the tab in the CELESTE tool dedicated to the geometry of a span (distance to the ground, distance to a point, distance to the counter-profile),
• Compliance of a staff with administrative assumptions.

/ Objective

• Identify the different surveying devices and equipment used at RTE,
• Set up a station at any point or at a specific point,
• Measure distances,
• Measure a parameter using the papoto method,
• Measure a parameter using the tangent sighting method,
• Exploit the results in the context of the activities of the support teams, i.e. in response to third-party urban planning projects,
• To rule on the conformity of a span with regard to the external distances to be respected in overhang and lateral.
