N2 - Traditional voltage transformers often encounter problems such as large size, insulation damage, and core saturation. Voltage sensors based on the electric field coupling principle avoid these problems. In early research, the method of changing the mutual capacitance between differential electrodes had many problems and was difficult to apply in practice. This study uses multilayer ceramic capacitors to replace mutual capacitance to create a new voltage sensor. Tests have shown that the sensor has excellent linearity and phase accuracy, and performs superiorly in high-frequency response. In addition, it offers the advantages of cost-effectiveness, compactness, shape adaptability, and easily adjustable voltage divider ratio.
