主 题：corrosion property grounding grids corrosion diagnosis ambiguous total least square touch and step voltages
摘 要：A new model considering corrosion property for grounding grids diagnosis is proposed,which provides reference solutions of ambiguous *** constraint total least square method based on singular value decomposition is adopted to improve the effectiveness of grounding grids diagnosis *** improvement can weaken the influence of the model s error,which results from the differences between design paper and actual *** influence on touch and step voltages caused by the interior resistance of conductors is taken into *** results show the validity of this approach.
