Validating theoretical hypothesis on access times and repair times statistical distributions for electric power distribution network

Data of interruptions of electric supply in electric power distribution networks and faults of their components were collected by utility company Iberdrola from several Spanish regions. After correcting and mixing these general data for building the histograms of the variables "times to access the faults" and "times to repair" for all data, it can be shown that these two histograms of a "generic component" may be approximated by an exponential distribution. This paper is part of an investigation project that is being done for the Spanish Electric Company Iberdrola SA.
