Assessing the situation of poles and crossheads (support parts of conductors (cables) of installed power on top of the poles) and, accordingly, deciding by the replacement of these facilities was the challenge that encouraged CPFL (Companhia Paulista de Força e Luz) to develop research that culminated in the creation of Smart Ultrasound equipment used to detect risks in power distribution facilities. Researchers at the dealership, of the State University of Campinas and company Agricef Soluções Tecnológicas started at the observation of premature removal of a large number of light poles due to the technical evaluation of the subjective conditions of resistance of these assets. With the equipment set up, the wooden or concrete poles were inspected by a technique that consists in determining, through speed ranges of wave propagation in the material, the ranges of mechanical properties to classify the material quality of the assets evaluated. The Smart Ultrasound can be used in the field because it has battery life of up to six hours. This allows, in addition to on-site inspection, the classification of new poles and crossheads. In tests, the hit rate in the removal of the posts was 93%, whereas the percentage of correct poles was diagnosed as good or very good, and which, therefore should remain in the network, was 100%. So, considering a margin of error of at most 5%, which is the standard of engineering, the use of the equipment would help in identifying crosses with resistance and undermined poles still in working order. The best accuracy of the evaluation has a direct impact on reducing the maintenance costs of the distributor, the postponement of premature investments and greater security in the distribution network. The patenting process of the Smart Ultrasound is in progress. It is intended to continue the search in the pioneer batch phase and, later, to obtain licensing of manufacturers to supply the product to distributors in the country.
