Diagnostics of the Technical Condition of Energy Devices based on the Monitoring of Phase Voltages and Currents

Abstract

In this article, in contrast to the existing devices and methods for diagnosing the technical condition of energy devices in industrial and mining enterprises, a control and diagnostic device ZM307A has been developed, which allows regular monitoring of phase voltages of large-power synchronous motors driving the working mechanisms of electrical technological devices. Based on the application of the developed ZM307A control and diagnostic device to synchronous motors, the system for diagnosing their technical condition has been improved. As a result, accidents related to phase voltages and phase currents of synchronous motors can be detected early and prevented. The ZM307A control and diagnostic device is also relevant for solving problems related to phase voltages of large-power synchronous motors in industrial and mining enterprises.
