DEVICE FOR PROTECTING AGAINST A SHORT-CIRCUIT FAULT IN AN ELECTRICAL NETWORK

摘要

The invention relates to a device for protecting against a short-circuit fault arising in an electrical network powered by a static converter configured to deliver a maximum fault current Id to control the tripping of at least one safety module having a tripping threshold current Isd and a tripping timeout duration Td. The device according to the invention comprises at least one module for aiding the tripping of said safety module if the maximum fault current Id is less than the tripping threshold current Isd during said timeout duration Td.
