Failure duration in distribution networks

摘要: The paper deals with statistical analysis of data on faults and failures in electrical power distribution. We used the statistical analysis of both MV overhead and cable lines, and electrical power stations of one distribution company. The data were collected from 2000 to 2009 with focus on the duration of failure with respect to different types of equipment. To compare and analyze the data, we used confidence intervals and also statistical distribution of data-sets.
