ANDRADE MALLEA, Carlos Eduardo. MANTENIMIENTO BASADO EN LA CONDICIÓN (MBC), APLICADO A UN ELEMENTO DEL SISTEMA DE PROTECCIÓN DE MEDIA TENSIÓN PARA SUMINISTRO DE ENERGÍA ELÉCTRICA: TÚNEL SAN RAFAEL, KM 6+257 A KM 7+641 KM TRAMO LA PAZ - LIMITE DEPARTAMENTAL CON EL BENI, CARRETERA COTAPATA - SANTA BÁRBARA. Rev. Tecnológica [online]. 2017, vol.13, n.19, pp. 21-23. ISSN 1729-7532.

The San Rafael Tunnel (length 1384 m) of the La Paz section - the departmental boundary with the Beni part of the fundamental route F-03, requires continuous supply of electrical energy that serves mainly for lighting, technical controls and traffic signaling, ventilation To the interior and of the emergency escape galleries. Supply that is fed through a medium voltage substation (24.9 Kv Pichu-Tunnel line) and from which it comes its transformation to (400 V), incorporating for its uninterrupted work a protection system, which like any system Electromechanical requires policies, plans and maintenance operations. Proposing therefore the application of the MBC (Condition-Based Maintenance) to one of its important elements (motor-reductor) taking into account the degree of criticality that it presents.
