Metodología de mantenimiento predictivo en redes de distribución de medio voltaje por medio de técnica de estudio termográfico

Abstract

In order to provide a quality, efficient and reliable electric service, electric distribution companies need to implement maintenance programs where the components involved in the operation are evaluated. Within the execution, the predictive type stands out, because it reduces the cost of executing corrective and preventive maintenance, it is specifically directed towards the failure before its occurrence, this provides a temporary lapse to act and make a correction prior to the possible damage to the service or partial stoppage. For prediction, use is made of specialized tools and diagnostic tests that do not affect the operation. The present work focuses on the application of the thermographic study due to its wide field of application, minimum risk and cost, therefore, a predictive maintenance scheme is proposed that allows analyzing anomalies in medium voltage electrical networks, evaluating their condition and proposing possible operational improvements. By means of this methodology, in first instance we proceed with the evaluation and analysis of the current state of the components of the networks under the use of the thermography camera, determining the condition and possible deterioration to establish technical aspects for the development of a methodology with the purpose of improving in the components their physical and electrical characteristics that integrally favor the operation of the distribution networks.
