Protection systems for minimising the consequences of an electrical internal arc when, in spite of alarm systems, an electric fault takes place in the device it is very important to minimize the damage caused from the internal arc. This can be obtained by means of pressure sensors able to signal (with a delay of 9-10 ms) the pressure peak which follows the internal arc. This signal operates immediately on the breaker that causes failure without waiting the longer operating time of the selective protections. This system don't need any electronic processing device and operates in a steady way directly on the tripping coil of the breaker which cause failure by means of a simple wired logics.
