Isolamento de motores elétricos
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia Industrial ElétricaUTFPR, 2014-11-27)
Eletric engines are extremely important for the production of an industry, and they can, with the use, develop defects or failures. So aiming to maximize its efficiency and to reduce maintenance costs, the predictive ...
optimal interval for major maintenance actions in electricity distribution networks
(ELSEVIER SCI LTD, 2009)
Many systems require the periodic undertaking of major (preventive) maintenance actions (MMAs) such as overhauls in mechanical equipment, reconditioning of train lines, resurfacing of roads, etc. In the long term, these ...
