Voltage sag segmentation under deformation tensor parameters

This paper introduces a new algorithm of polyphasic segmentation. This new algorithm combines the strength of the concept of voltage signal tensor with the benefits offered by the residual segmentation technique in order to generate a unique pattern of segmentation. This segmentation strategy is validated using a set of synthetic signals with voltage variation in the remnant voltage and the start point of the event. The proposed algorithm is tested using a set of real signals captured by a local network operator.
