    Abstract: A fail-safe motorized switching system includes: (a) a motorized loadbreak switch system, the motorized loadbreak switch system adapted for opening and closing contacts between a high voltage power source and a load; (b) an energy storage device connected to the motorized loadbreak switch system; and (c) a controller connected to the energy storage device, the controller programmed with control logic to ensure that the motorized loadbreak switch system opens the contacts between the high voltage power source and the load once the power source is removed.

    Abstract: A variable frequency drive system for controlling the frequency of a high-voltage power source supplied to a first electric motor includes a transformer section that includes a motorized loadbreak switch system, control power transformers, a controller programmed with control logic to ensure that the motorized loadbreak switch system opens contacts between the high-voltage power source and the variable frequency drive system once the power source is removed, and a tank containing a dielectric fluid, wherein the tank also contains, within the dielectric fluid, a manual isolation switch to supply or remove power to the transformer section, an impedance for use in soft-starting the variable frequency drive system, a primary winding, and a plurality of phase-shifted secondary windings.
