Status and prospects of implementing monitoring systems and technical diagnostics of electrical machines and devices

An analysis of modern methods and tools for monitoring and diagnosis of technical condition of asynchronous and synchronous motors and advice on choosing the best monitoring systems for use on existing and disabled equipment. It is shown that, based on measurements of basic parameters of complex by a single system of control, maintenance and repair of electrical machines, produced on their technical condition with no planned outages, and intrusion prevention tests.
Materials and methods
Along with classical parameters for assessing the technical condition of electric machine used the phase and frequency parameters.
Conclusions
1. The analysis of the basic concepts of existing solutions to establish monitoring systems of high-power electrical machines. It is shown that the monitoring system based on signature analysis of stator currents, solve the task. 2. Noted that the use of monitoring systems based on a wide scope of control parameters should be taken into account already at the stage of designing and manufacturing electric cars. The monitoring system should include the necessary amount of important and reliably controlled parameters that protect electrical machines from serious damage. Due to poor interference immunity in monitoring system of partial discharge measurements include irrational. 3. Problematic link in the creation and successful application of monitoring systems, is an interpretation of the obtained data, the absence of such developments and the main obstacle is the introduction of monitoring systems in practice. 4. Rapid detection of encountered defects after disconnecting the electrical machine should be placed on other, mobile system, which can be considered as the second level monitoring system. 5. Application of integrated systems for diagnostics of electric motors, including multiparameter methods allows you to implement a technology hardware maintenance on actual condition relevant to domestic energy.
