Abstract: A coil actuator for a low and medium voltage switching apparatus comprising a coil electromagnet (2), a power and control unit (3), which comprises a power circuit (31) operatively connected to said coil electromagnet (2) and a processing unit (32) operatively connected to said power circuit and controlling the trip of said coil electromagnet (2) through said power circuit (31). The power and control unit (3) comprises an optical port (30), which is suitable to be operatively connected to an optical fiber cable (112), and a first detection unit (33), which is operatively connected to said optical port and to said processing unit. The first detection unit (33) is suitable to receive a light signal (L) from said optical port and to output a first detection signal (D1) indicative of the presence of an arc fault, depending on said light signal. The processing unit (32) is suitable to receive said first detection signal (D1) from said first detection unit and to control the trip of said coil electromagnet (2), depending on said first detection signal. In a further aspect, the invention relates to an arc fault coil suppression device including said coil actuator.

Abstract: A combined measuring and detection system is disclosed which includes an electronic evaluation unit for analyzing a broad frequency spectrum of measured quantities and one or more measuring devices for measurement of one or more of a magnetic field, an electric field, a current, and a voltage. The measuring devices are operatively connected to the electronic evaluation unit, which is provided with at least one frequency splitter dividing the measured quantities into a low frequency component and into a high frequency component. Low frequency components are used for measurement and protection analysis and high frequency components are used to detect partial discharges activity.

Abstract: An electronic system is disclosed for an associated electrical apparatus, the system having at least a binary input adapted to receive one or more candidate signals; at least an electronic active load having one or more electronic active devices and operatively connected to the binary input; and a controller operatively associated to the binary input and to the active load. The controller can detect application of a candidate signal to the binary input and electrically drive the active load upon such detection; and after absorption of a predetermined amount of energy, validate the candidate signal if its residual content of energy exceeds a predetermined threshold.
