Abstract: A method for performing recloser operations at a transfer switch includes obtaining an input from a first sensor measuring characteristics at an electrical conductor connecting a main power source to a load, comparing the input to one or more thresholds, cycling a first switch between an OFF and ON position for one or more cycles, determining the input exceeds the one or more thresholds when the first switch is cycled ON, and connecting the load to the main power source with the first switch in response to the input being within the one or more thresholds, or connecting the load to a second power source with a second switch in response to determining the input exceeds the one or more thresholds after the one or more cycles. The input may include a source voltage and the one or more thresholds may include an upper and lower voltage threshold.

Abstract: A transfer switch for hybrid switching between a first power source and a second power source, the transfer switch includes a first switch and a second switch, the first and second switch connecting a load to a first power source and a second power source, respectively. The first switch includes at least one first solid state switching device (SSSD) pair. The second switch includes at least one second SSSD pair. The at least one first SSSD pair includes a different type of switching devices relative to the type of switching devices of the at least one second SSSD pair. Moreover, a controller may be configured to selectively cycle the at least one first SSSD pair and the at least one second SSSD pair on and off to electrically couple one of the first power source and the second power source to the load.
