Field tests of a robot system prototype for the underground distribution lines

This paper describes a R&D project at Hydro-Québec's Research Institute (IREQ) regarding the development of a mobile robot for underground distribution lines. It discusses the advantages of a robotic system for the operation and maintenance of power distribution lines. The tasks to be performed on a Joslyn load break switch located in an underground vault are given, and the prototype of the robot system with its main sub-systems is presented. Field tests with this robot system at IREQ's vault and at a de-energized vault of the distribution network in Montreal are commented.
