The main problem of a bolted current-conducting connection is the mechanical weakening of the contact density of the adjacent surfaces of busbars, cable lugs, switching equipment connections, etc., which causes an increase in contact resistance of the contact, as a result of which the load current flows through it Joule-Lenz law, there is overheating of the connection. Development of methods for non-destructive testing of diagnostics of the state of a bolted current-conducting connection, which allow timely detection of a pre-emergency situation regardless of the magnitudes and mode of the current load and the ambient temperature. The solution of the task is relevant, in connection with the transition of enterprises from the system of planned preventive repairs to repairs according to the actual state of the object. The nature of the change in current load is due to the technological mode of operation of the equipment, and the stationary and deterministic nature of the change in current is a special case of a non-stationary mode. Changes in the magnitude of the current discretely, monotonously decreasing or increasing will lead to the appearance of a transient process of heating and cooling the bolted current-carrying connection, at which the temperature of the bolted current-carrying connection will vary in a decreasing or increasing exponential relationship. The change in ambient temperature also monotonously increases or decreases. In the modes of non-stationarity of the current load, it is important to identify areas of stationarity. The diagnostics of the emergency mode of current-carrying attenuation describe the estimated Boolean functions that take into account changes in load current and ambient temperature. For non-stationary current modes, detecting the initial moment of a contact current-carrying bolted connection is possible only in the area of simultaneous stationarity of monitored values. The timely detection of the initial moment of loosening of the bolt-conducting connection allows you to move from the CPD system to the electrical equipment maintenance system upon the detection of a defect.
