Inherent Time-Delay Determination for Acquisition Module of Electronic Transformer

This paper presented an approach to measure the inherent time-delay for electronic transformer acquisition module. Traditionally, the inherent time-delay measure is a complex task and the accuracy is low. Based on the time-scale mobile and the DFT methods, in this paper, an inherent time-delay testing system has been designed to measure high accuracy time-delay in electronic transformer acquisition card and merging unit. Experiment studies are given to verify the effectiveness of the proposed method.
