Increasing the Efficiency of Contactless Functional Diagnosis of Complex Electrical Equipment

One of the main ways to increase the efficiency of operation of electrical equipment (EE) of various applications is the improvement of methods and means for monitoring parameters, diagnosing and predicting its health. Recently, there has been a steady interest in the development of methods that allow to implement the functional control and diagnostics directly in the process of operating EE in a regular structure for a real load. Most often, contactless methods based on various physical principles are used for these purposes. The proposed work is devoted to the problem of increasing the efficiency of contactless functional diagnostics of electrical equipment with complex shape of input current. This goal is achieved by using current signal gating and extracting from it a section responsible for the operation of the diagnosed node.
