Abstract: The present application provides a residual-current protection device and a tripper. The residual-current protection device comprises: a flux transformer receiving a residual-current signal; a tripping output element outputting ON/OFF signals; an energy storage mechanism adapted to switch between an energy storage state and an energy release state, the energy storage mechanism having a locking unit that locks the energy storage mechanism in the energy storage state; and a transmission mechanism braked by the flux transformer, which drives the tripping output element to move and drives state of the energy storage mechanism to switch; the transmission mechanism comprising: a first rack cooperating with the locking unit, a second rack driving the tripping output element, and a reduction gear with a big gear engaged with the first rack and a small gear engaged with the second rack. By means of the gear rack transmission mechanism of the residual-current protection device, reduction transmission can be effected, driving force needed by energy storage may be reduced, and thus design requirements as high transmission efficiency, easy processing and assembly as well as low costs can be satisfied.

Abstract: A method for identifying a fault event in an electric power distribution grid sector including one or more electric loads and having a coupling node with a main grid, at which a grid current adsorbed by said electric loads is detectable. The method allows determining whether a detected anomalous variation of the grid current, adsorbed at the electric coupling node, is due to the start of a characteristic transitional operating period of an electric load or is due to an electric fault.
