When a power outage occurs, an uninterruptable power supplies may lose all grid connections including a neutral connection which may be connected to ground. To avoid the loss of a ground connection to the power circuits of the UPS, a switch unit may be used to selectively connect a neutral conductor of the circuit to a ground terminal. The switch unit may comprise a power relay, a fast switch device (FSD), and a controller. The power relay and FSD may be connected in series between the neutral conductor of the circuit and a ground terminal. The controller may be configured to: close the FSD when the voltage between ground and neutral (Vng) goes above a first threshold, open the FSD when the voltage between any grid connection and neutral (Vg) goes above a second threshold, and close the FSD when Vg is below the second threshold.

Systems, apparatuses, and methods are described for electrical switching. In some examples, electrical switching is performed by a plurality of switching arrangements. The plurality of switching arrangements may be connected in parallel to one another.

Method and apparatus for electrical switching

Systems, apparatuses, and methods are described for a versatile UPS. The versatile UPS is operative to provide power to a load and to an interconnected network for delivering electricity from producers to consumers (i.e., an electricity grid, or simply, 'a grid'). The versatile UPS has a plurality of switches providing for a multiplicity of switching states. The output to the load, the grid, or both is dependent, at least in part, on the switching states. Related systems, methods and apparatus is also described.
