| Abstract: | Aiming at the disadvantages of single detection methods of earth fault,the method of earth fault detection in small current grounding network based on evidence theory was put forward.Six typical fault cases were simulated and the fault measures of each line in all kinds of fault cases were found.The simulated result indicated that the method of earth fault detection in small current grounding network based on evidence theory could detect the fault line correctl.The method could be used widely and had good r... |
