Isolamento de motores elétricos

Abstract

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 maintenance is growing up with the goal of early detection of faults. The purpose of this work is to develop a spreadsheet, through studies and practices, which would help operators of maintenance in the engine insulation resistance tests. Aspects such as dirt and moisture can be detected by this test values.
