Features of the Construction of Autonomous Diagnostic Systems of Electrical Equipment, Taking into Account the Modes of Its Operation

The structure of the diagnostic system is proposed. The energy harvesting (EH) technology is used to provide the functioning of autonomous measuring transducers which located on the parts of the electric machines (EM) in the system. It provides the possibility to carry out the power supply of electronic circuits in autonomous devices for measuring vibrations due to the transformation into the electric current of the mechanical energy of the vibration of the EM unit. The necessity of forming of the spaces of diagnostic features, taking into account the operating modes of the objects under study, has been proved at the examples of investigation of the vibration of bearing units of auxiliary engines. The obtaining of experimental data is carried out using a laboratory diagnostic system. It includes measuring transducers, functioning of the cat-rick is provided with the help of autonomous power systems.
