| Abstract: | Through field investigating the tower earth net,the cause of tower with rather high earth resistance in high soil resistivity area,where the Hubei UHV transmission lines passing through,was summarized.The conventional reducing resistance measures with theoretical calculation were studied.The effective reducing resistance measures suitable for the real situation of Hubei high soil resistivity area were put forward.The typical towers were selected to make earth net reducing resistance modification.The modifie... |
