Abstract: Apparatuses and methods for passively monitoring the integrity of current sensing devices and associated circuitry in protective devices such as Ground Fault Circuit Interrupters and Arc Fault Circuit Interrupters are provided. A protection circuit interrupter employs a capacitively coupled noise signal obtained by an arrangement of one or both of the line side arms relative to a Rogowski coil. The noise signal is monitored while the line and load sides of a protective circuit interrupter are disconnected, and the connection of the line and load sides disabled if the noise signal fails to correlate sufficiently to a reference noise cycle. When the line and load sides are connected, the RMS value of the observed current signal is monitored such that the line and load sides are disconnected if the observed current signal fails to meet an RMS threshold.

Abstract: The present invention provides a linear motor, wherein, a coil is fastened on a mass block that is suspended inside a housing, and a magnet is fastened on the housing and thus does not move during use. In the linear motor of the present invention, the design route that utilizes coil motion to drive mass block motion is different from the traditional route that utilizes magnet motion to drive mass block motion, thereby the traditional “moving-magnet type” is changed into “moving-coil type” of the present invention. When the linear motor provided by the present invention is used in a highly magnetic environment, even if magnetic shield plates for shielding external magnetic induction lines are glued on both outer sides of the housing, because the magnet is fixed stationary itself, no vertical deviation of the magnet due to influence of the shield plates like in the prior art occurs.
