Abstract
An automatic control transfer device for selectively energizing an electrical distribution system from a pair of electrical power sources. The device includes means for sensing electrical conditions on both of the sources and programmable electronic digital logic to selectively energize associated circuit interrupters for switching a distribution system between the two sources. A plurality of time delay functions are provided utilizing a separate oscillator for each function, each oscillator providing input to a common digital counter. The device senses the status of associated circuit interrupters to provide interlocking and lockout functions as well as proper switching commands for either two- or three-circuit interrupter systems. Means are also provided for testing the entire device without initiating an actual source transfer.
