Abstract:The calculating process of differential variable and restrained variable on differential restrained curve are introduced, and the necessity of filtering zero part is analyzed. The ratio restrained theory of transformer protection relay-T60 is discussed, and the theory and the calculation formula of magnitude compensation, phasor compensation and the filtering of zero-current are analyzed. The curve of differential restrained characteristic is analyzed, including the transition curve and the setting of the ratio restrained characteristic.
Keywords:differential protection  ratio restrained characteristic  transformer  differential variable  restrained variable
