Abstract The article presents a theoretical analysis of electromagnetic compatibility (EMC) and experimental measurement of effects of radiation and acoustic emission of high-voltage transformers for electronic equipment and working personnel in a control room. Electromagnetic compatibility and safety of equipment are not considered as two distinct areas of study in electric and electronic safety. Economic criteria cannot compromise safety but at the same time immunity levels must be relevant in order to establish a “Functional Safety”. Introducing Special Immunity Levels in the level of equipment testing allows us to combine the two areas of EMC and safety. The measurement was carried out in high-current of very high-voltage distribution station. A real-life analysis of effects of electric and electromagnetic field was carried out. FFT was used for mathematical processing of data which were later presented in a graphical form of a spectrally analyzed area. In the last part of the paper we discuss the suitability of acoustic camera to perform contactless monitoring of the health and operation conditions of the power transformer by analyzing acoustic field generated by the transformer core and windings in near control room.

控制室电磁兼容性及辐射分析

摘要 本文介绍了电磁兼容性（EMC）的理论分析和高压变压器辐射和声发射效应的实验测量，用于电子设备和控制室工作人员。设备的电磁兼容性和安全性不被视为电气和电子安全的两个不同研究领域。经济标准不能危及安全，但同时免疫水平必须相关，以建立“功能安全”。在设备测试级别引入特殊抗扰度级别，使我们能够将 EMC 和安全这两个领域结合起来。测量是在特高压配电站的大电流下进行的。对电场和电磁场的影响进行了实际分析。FFT 用于数据的数学处理，这些数据后来以光谱分析区域的图形形式呈现。在论文的最后一部分，我们通过分析控制室附近变压器铁芯和绕组产生的声场，讨论了声学摄像机对电力变压器的健康和运行状况进行非接触式监测的适用性。
