With the continuous development of nuclear power technology,the requirements for electromagnetic compatibility in nuclear power instrument control systems are also constantly increasing.If the system does not have sufficient electromagnetic compatibility,it will compromise its safe and stable operation.Therefore,it is particularly important to obtain accurate and reliable electromagnetic compatibility measurement results,and the accuracy and reliability of measurement results are closely related to the uncertainty of measurement results.At present,there is no article that provides a detailed analysis and calculation of the sources of uncertainty components in conducted emission testing.This paper studies the types of measurement signals,equipment measurement principles,and testing pathways,and presents a mathematical model and a complete method for evaluating uncertainty.It provides a valuable reference for uncertainty evaluation in the field of emission in nuclear power instrument control system laboratories.
