ENGINE FAULT DETECTION SYSTEM BASED ON HIGH-FREQUENCY SIGNALS SUPPLY BY MEANS OF COMMUNICATION Russian patent published in 2020 - IPC G01R31/34 

FIELD: test equipment.

SUBSTANCE: invention relates to test equipment, in particular to systems for electrical testing of engines in order to detect faults. Engine failure detection system is developed based on high-frequency signal supply by means of communication, input end of engine is connected to high-frequency signal source detection circuit through communication circuit for supplying high-frequency detection signal to motor winding; input end of the high-frequency detection signal source circuit is connected to the output end of the controller for controlling the output of the high-frequency detection signal; output end of processing circuit of response signal is connected to input end of controller to send received response signal voltage or current to controller; controller evaluates whether the engine has a fault, as well as the degree of failure by analyzing the response signal after applying excitation.

EFFECT: system detects engine malfunction without stopping its operation.
