A method and system of reducing the time that a load remains un-powered when a power source fails is disclosed. The method includes receiving a sinusoidal input signal from a first power source. Once the signal has been received, a sinusoidal output signal is generated. The sinusoidal output signal defines a lower limit of a deviation range over which the sinusoidal input signal can deviate before a source-transfer from the first power source to a second power source is initiated. Input signal instantaneous value is compared with output signal instantaneous value. When the input signal instantaneous value has fallen below the lower limit of the deviation range is detected, a digital signal is sent to a switch controller in response to the detection, the digital signal causing the load to be coupled to the second power source.

THREE-POSITION APPARATUS CAPABLE OF POSITIONING AN ELECTRICAL TRANSFER SWITCH
A multi-position apparatus for use with a system operated in at least three distinct positions. The apparatus comprises (i) a position-selection mechanism, (ii) a first link mechanism and a second link mechanism, each link mechanism being operably coupled with the position-selection mechanism, (iii) a first weight-actuated spring mechanism operably coupled with the first link mechanism, (iv) a second weight-actuated spring mechanism operably coupled with the second link mechanism, (vi) a first output- actuating member operably coupled with the first weight-actuated spring mechanism, the first output-actuating member being arranged to operably communicate with the system, and (vii) a second output-actuating member operably coupled with the second weight-actuated spring mechanism. In one example, the system may be an electrical transfer switch having two separate set of electrical contacts.

Method and apparatus for parallel engine generators
A method and apparatus for paralleling engine generators. One or more closed transition transfer switches (CTTSes) are coupled to two or more engine generators. A system controller is programmed to operate the one or more CTTSes so that each of the generators provides an emergency power and so that the generators may simultaneously supply emergency power to the power bus.
A system and method are presented to detect and account for regenerated voltage in a three phase power source failures. The method involves monitoring a power source for phase voltage unbalances to determine the presence of a single phase failure. If the voltage unbalance caused by the single phase failure is restored before a sensing timer expires, a regenerated voltage condition is detected and retransfer to the power source is inhibited. Retransfer to the power source may be delayed by a period determined by a retransfer time value, in order to prevent transfer cycling between the preferred power source and an alternate power source. In addition, retransfer inhibiting may be terminated due to user interaction, power source voltage readings indicating a repair state, or by failure of an alternate source.
