1. IntroductionGrid electronic voltage transformers, as indispensable measuring components in power systems, have their measurement accuracy directly tied to the stable operation and efficient management of power systems. However, in practice, due to the inherent characteristics of electronic components, environmental factors, and limitations of measurement methods, the measurement results of voltage transformers often involve uncertainty. This uncertainty not only impacts the accuracy of power

1 Overview of EMC Performance of Electronic Voltage Transformers1.1 Definition & Requirements of EMCElectromagnetic Compatibility (EMC) denotes a device/system’s ability to operate undisturbed in a given electromagnetic environment and avoid causing unacceptable electromagnetic interference to other entities. For electronic voltage transformers, EMC demands stable measurement performance in complex settings, without interfering with other devices. Their EMC performance must be fact
