Abstract The medium voltage electrical system of a nuclear power plant is a 6.6kV neutral point ungrounded system. Based on an example of a ferromagnetic resonance of an auxiliary power system that actually occurs in the power plant, through modeling calculations, the cause of ferromagnetic resonance of voltage transformer excited by external factors is analyzed. The corresponding preventive measures are formulated, which provides a strong external power supply guarantee for the safe and reliable operation of nuclear power plants.
