AN IMPROVED CURRENT SENSING DEVICE FOR LOW-VOLTAGE POWER CIRCUIT BREAKERS
摘要
A current sensing device, particularly for low-voltage power switches, whose particularity consists of the fact that it comprises: multiple magnetic field sensors which are suitable to be arranged around at least one current conductor element whose current measurement is to be obtained, the sensors performing a spot measurement of the magnetic fields; signal processing means which are suitable to receive current measurement signals which arrive from the multiple magnetic field sensors; the positioning and orientation of the multiple sensors around the at least one conductor element being determined so as to optimize the measurement precision of the sensors.
