New IEEE Standard - Active. Sound is generated by a high-voltage reactor during operation due to vibration with the action of electrical and mechanical stress. Rich state information about the reactor is contained in these sound signals. Therefore, the evaluation of equipment status can be aided by the measurement and research into reactor sound signals. A solid technical foundation for locating abnormal noise in reactors is also provided by the development of acoustic imaging technology. Acoustic imaging technology allows researchers to obtain the distribution of the sound field of a reactor with a microphone array. Combined with knowledge of the reactor structure and operating status, the position of a sound signal and the status of reactors can be effectively determined by researchers with this technology. The characteristics of acoustic imaging technology include noncontact measurement, simple operation, and flexible arrangement. The measured results are important for diagnosing reactor status and identifying sound sources. To guide and provide instructions for the testing of on-site acoustic imaging for reactors, this guide is formulated to specify the test methods, provide the basic requirements, and describe the test instruments, procedures, test data analysis methods, and data records, while providing guidance for the testing of acoustic imaging for reactor.
