Application of robotics in substations | ELECTRA

IntroductionScope and MethodologyDescription of TBSubstation Operation RobotsConclusionTraditional life-cycle management of substations requires significant manpower and is typically hindered by issues pertaining to efficiency, consistency, quality, and safety (especially in high voltage environments), which can be further compromised by severe climate conditions and at difficult to access locations. Substation owners, asset managers, and engineers are always looking for ways to achieve highest levels of safety and minimizing the costs of substation construction, operations, and maintenance. These goals can be achieved by employing robots. Rapid advancements in artificial intelligence and sensor technologies lead to development of robotics, which could replace or assist people in substation operations and management. Some of these robots are already used in substations, with excellent results. This Technical Brochure (TB) provides an overview of the existing applications of robotics in substations. It also presents the current and future trends in the development of n...Get price
