A Detection Method for Fast Electrical Impedance Imaging of Grounding Grid Based on Optimized Differential-Multigrid-Homotopy Algorithm

Efficient electrical impedance imaging fault detection in grounding grid is necessary. In this article, we propose an optimized differential-multigrid-homotopy (MG-HT) algorithm for grounding grid impedance imaging. To enhance the iteration speed, we introduced an optimized differential algorithm to...
