Abstract

Wood is widely employed to support aerial cables for electrical energy and telecommunication networks. Being a natural material, it is subject to decay, which requires periodic structural inspections. This paper present the metrological analysis of a vibration-based pole testing system, taking into account different contributions to uncertainty as well as the effects of natural variability of wood properties. The study allows to evidence the main features and intrinsic limits of the test approach and shows how performance bounds have been evaluated.
