Abstract
A system for managing an insulation fault in an electrical installation includes a monitoring device, measuring devices configured to measure an electrical quantity in the installation, and switches controlled by the monitoring device. The monitoring device is configured to: detect a first insulation fault in the installation; detect a second insulation fault in the installation; and automatically control one of the switches associated with output terminals so as to open in order to eliminate one of the detected electrical faults, the switch to be opened being chosen depending on the location of the detected insulation faults and on predefined control laws making it possible to disconnect only some of the electrical loads.
