The protection of property and people requires the establishment of a protection plan and the setting of protective equipment. Obviously, these must respect certain principles of selectivity.
For this purpose, Capsim performs defect current calculations to evaluate the minimum and maximum values that the protections must eliminate. Then you have to analyze the existing voltage plan or create a new one. This is used to determine which protections should act.
The tuning and analysis of these studies consists of building current / time curves to verify the selectivity.
Depending on the result, Capsim validates, adjusts, or sets a new strategy for the voltage plan.
Requirement As part of the construction of the Severstal industrial site in Russia, Capsim carried out a selectivity study of the protection plan of all the HV and LV electrical grids. Realization The input data Read more…
Requirement The site studied was a very large facility undergoing reconversion that would result in it accommodating new consumption units and new generators (biomass plant) using the existing electrical grid. In this configuration, the operator, Read more…
Requirement The distribution grid of the Arsenal de Toulon is one of the largest private grids in France with more than 150 transformer stations. Because of the obsolescence of certain protection devices and the limitations Read more…
