Abstract: The method for controlling selectivity of electric equipment comprises: communication of electric equipment settings between at least one electric equipment unit and a data processing device, computation of the selectivity of electric equipment according to said electric equipment settings, storing and communication of data representative of the selectivity settings and data, supervision of changes of settings and/or of changes of equipment, and checking of the compatibility between new settings after a change and the selectivity computation. The device and installation comprise means for implementing the selectivity control method.

Abstract: Method for performing maintenance of an electric installation including at least one electric equipment unit comprising: entry and storing in a database of data representative of an electric installation to be monitored and of data representative of electric equipment settings and parameters, storing of data representative of events in a database so as to constitute an events history, detection of malfunctioning disturbances, analysis of causes of malfunctioning of the electric installation, management of restoration of operation of a part of the installation. Management of restoration of operation comprises monitoring by a decision tree to evaluate a criticality level.

Abstract: A monitoring method, device, and electric installation for monitoring ageing of at least one electric equipment unit. The monitoring method includes entering and storing ageing computation data by type of equipment, measuring physical quantities representative of environmental conditions of the electric equipment unit, the measuring of the physical quantities including measuring humidity content with a humidity sensor and measuring salinity content with a salinity sensor, computing ageing according to the measured physical quantities including the humidity content and the salinity content, and according to the stored ageing computation data, and generating electric equipment ageing data that indicates the ageing of the electric equipment unit.
