LOW ENERGY RECLOSING PULSE TEST

A method for performing a low energy pulse testing in a power distribution network that causes contacts to close and then open in about one fundamental frequency cycle of current flow time and close on a voltage waveform that produces symmetrical fault current. The method includes energizing a magnetic actuator to move the actuator against the bias of a spring to move a movable contact towards a fixed contact. The method also includes de-energizing the actuator when the movable contact makes contact with the fixed contact so as to allow the spring to move the movable contact away from the fixed contact so that the amount of time that the current conducts is about one fundamental frequency cycle of the current, where energizing the magnetic actuator occurs when an applied voltage on the switch assembly is at a peak of the voltage wave so that the current is symmetric.

Magnetically operated switches and methods of making magnetically operated switches

Magnetic orientation-independent magnetically actuated switches may be made by producing an outer cylinder and an actuator cylinder from ferromagnetic sheets and non-ferromagnetic sheets in alternating order. A first ferromagnetic body is attached to an end of the outer cylinder. The actuator cylinder is positioned within a first bore of the outer cylinder, the actuator pin is positioned within a second bore of the actuator cylinder and a third bore of the first ferromagnetic body with a portion of the actuator pin extending beyond the third bore of the first ferromagnetic body. A second ferromagnetic body is attached to the portion of the actuator pin, thus forming the magnetic orientation-independent magnetically operated switch.
