The ground resistance, the ground potential rise, touches and step voltages are the basic design quantities of the grounding grids. Such quantities greatly depend on the safety of grounding system. The aim being pursued is to minimize these mentioned quantities, while the safety restrictions required by the standard regulations are met. The innovative aspect of the proposed approach is the influences...
To improve the efficiency of the corrosion diagnosis, based on the hierarchical model, an actual grounding grid can be divided into six levels, such as actual grids, quasi- circuit-domain, circuit-domain, circuit-network, touchable network and intrinsic network. Based on above model, a novel node partition based approach is put forward. In which, a grounding grid is divided into several small-scale...
To benefit the fault detection and identification of conductor corrosion fault, a hierarchical simplified model of grounding grids is put forward. Minimum unit dividing is the key process of hierarchical simplification, which can be realized by the proposed algorithm. Branches are classified into clear branch and uncertain branch. A Monte-Carlo based testability evaluation approach is suggested. The...
