Benefits of monitoring the rotor electrical quantities and transmitting by wireless communication

Industrial applications are every day demanding more quality, efficiency and operational availability of their rotating machines. Therefore, monitoring the electrical quantities from a synchronous motor´s or generator´s rotor, and transmitting this data via wireless communication is highly desirable for monitoring operating conditions and preventing critical failures. Analysis of rotor operation that was previously derived from assumptions and deductions based on measurements external to the machine can now be confirmed with this new technology. This paper discusses the use of this technology to transfer data collected on the rotor of an electrical rotating machine via wireless telemetry, demonstrating how crucial and efficient this technology is for event analysis in large synchronous motors for industrial applications.
