Abstract (en)

[origin: WO9636982A1] A current interrupter (4) includes a current interrupting device (4) having at least one movable contact (71); an actuator (8) coupled to the movable contact (71) of the current interrupter (4); a feedback sensor (14) for monitoring movement of the actuator (8); and a control system (12) coupled to the feedback sensor (14) so as to receive information from the feedback sensor (14) concerning the movement of the actuator (8) and for controlling movement of the actuator (8) based on the information. The interrupter (4) further includes a memory (202) for storing a desired motion profile of the actuator (8); and a microprocessor (202) for comparing the movement of the actuator (8) with the desired motion profile and controlling movement of the actuator (8) based also on a comparison of the movement of the actuator (8) with the desired motion profile. The interrupter (4) further includes a sensor (204) for sensing a waveform of a voltage in a line to be interrupted and providing information concerning the voltage waveform to the control system (12); wherein the control system (12) controls the movement of the actuator (8) based also on the information concerning the voltage waveform.
