Manutenção preventiva como função estratégica para ativos de subestação de média tensão: estudo de caso em empreendimento hoteleiro.

Abstract

The supply of electricity in industrial, commercial enterprises and service is essential for companies to achieve their goals financial and quality. Any unexpected stoppage of this input may cause irrecoverable damage. Aiming at the continuity of this input so important in undertakings, this technical article will present the main machines and equipment of a medium power substation consumer voltage, detailing the operation and specifying the main services, tests and measurements applied in a maintenance preventive. The results found in a trial of insulation resistance of a dry power transformer and also shown the measured values ​​of power quality for electrical voltage and power factor. In addition, the study shows a predictive test of thermovision in this same substation model. Through a study of case was shown the sequence of procedures for maintenance in compact cubicles of a medium voltage substation pointing irregularities found in this preventive maintenance.
