The Risk Analisys for the Coexistence of Overhead Lines and Urban Green Areas

The key challenge of smart cities is the need to satisfy the conditions for a safe distance between the buildings, streets, or green areas (public gardens) and the classical high voltage overhead line. If the interference effects are high enough, they may pose a safety hazard to personnel or the public or may compromise their integrity. This paper is the result of the authors expertize that determines how close to high voltage power lines, public gardens can be used. The coexistence study is a technical-economical documentation in which both mechanical and/or electrical assumptions of the overhead lines are delimited based on inspections, calculations, measurements, etc. The location of other capacities or networks on the elements of the corridor or its protection and, where fitting, the obligation expected to satisfy the conditions of coexistence granted for by the rules and the costs of such operations. This research has been limited to generally available materials. Finally, to highlight the impact and risk analysis provided by the coexistence between the high voltage power line and urban public gardens a real study case is presented.
