    Abstract: An arrester and a method for producing an arrester are disclosed. In an embodiment the method includes providing at least three green layers, wherein each layer includes at least one green sheet, introducing at least one hole into a first layer and applying an electrically conductive material for forming inner electrodes to a second layer and a third layer. The method further includes laminating the layers to form a green stack, wherein the first layer is arranged between the second layer and the third layer, separating the green stack into individual components and compacting the individual components, wherein laminating the layers and compacting the individual components are effected in a single temperature process by co-firing.

    Abstract: A spark-preventing element embedded in a printed circuit board includes a capacitive output electrode, a capacitive input electrode, an interlayer conductive member electrically connecting the capacitive output electrode to a signal line, and an interlayer insulation member electrically insulating the capacitive input electrode from the signal line, The capacitive input electrode is spaced apart from the capacitive output electrode with an air gap disposed between the capacitive output electrode and the capacitive input electrode, surrounds the capacitive output electrode, and is electrically connected to the ground layer. The spark-preventing element has an improved electrical characteristic and an increased durability.

    Abstract: Method and system for controlling and limiting the damage caused by arcs formed on exposed conductors in electrical distribution equipment involve using the tendency of an arc to move in a direction away from a current source and toward the terminal ends of the conductors. An arc interruption device, or arc interrupter, is placed over the terminal ends of the conductor to capture the arc as it travels toward the terminal ends of the conductors. Within the arc interrupter, the shape of the arc is conformed to geometries designed to stretch and extend the arc to the point where it can no longer be sustained and is extinguished.
