Induction motor protection device

Abstract

Modern enterprises successful operation depends on reliability of working machines electric drive. Most often, the electric drive is an induction motor, which has a simple structure and is a reliable electric machine. However, there is a relatively high percentage of induction motors failure due to specific conditions and modes of operation, which were not taken into account in the design. Failure of electric motors leads to significant financial costs. Standard electric motors protection devices do not allow to carry out continuous control of operation therefore electronic diagnosing devices development of electric motors operating modes is actual.
