The embodiment of the invention, which belongs to the technical field of voltage sag processing, provides a voltage sag display method and apparatus. The method comprises: when a monitored voltage-sensitive device generates a voltage sag, a voltage sag root-mean-square waveform of the voltage-sensitive device is obtained; on the basis of a preset voltage sag energy function, the voltage sag root-mean-square waveform is converted into a voltage sag energy function curve, and a preset voltage withstanding curve of the voltage-sensitive device is transformed into a reference energy function curvebased on the preset voltage sag energy function; and the preset voltage sag energy function curve and the reference energy function curve are displayed in an overlapped manner in a same coordinate system. According to the invention, the mode of displaying the voltage sag influence visually and accurately by using a preset voltage sag energy function can be applied to various voltage-sensitive devices widely, so that the method for evaluating and displaying the voltage sag is applied widely.
