This paper presents a unique method for analysing voltage dips and swells using differential geometrical algebra. Differential geometry has been applied to interpret synthetic electrical signals as curves. This is possible since the instantaneous amplitude of a sinusoidal wave can be defined as a curve. This strategy is based on the rotating Frenet-Serret (TNB) frame, defined at each point along the curve. It serves as the basis for the method. Because the Frenet Frame is only locally specified for a curve if the derivative components are present, the moving frame velocity represents the changes in the events in the system. This method provides a better comprehension of circumstances such as sag and swells in contrast to prior methods that utilised the Clark and Park transformation to extract the event information and represent it using ellipsoidal geometry.
