Abstract:

This paper analyses possibility for obtaining of synthetic information about current transformers from substations, using statistical processing of current exploitation data: incidents recorded, results of measures and of tests, derogations, periodically maintenance. Thus, determination of extreme value, of mean value and of square mean deviation can lead to significant conclusions from view point of exploitation activity policy. There are presented results obtained for current transformers in the 400/220/110 kV substations from Moldova.

Keywords:

current transformers, data base, processing data.
