Abstract
Improvements introduced in an automatic transfer control apparatus for the selective excitation of an electrical distribution network from a pair of electric current sources by means of associated circuit breakers, comprising a first source detector for detecting the electrical parameters in the first source of electrical current, a second source detector for detecting the electrical parameters in the second source of electric current, a plurality of output control signal generators for the associated circuit breakers to selectively connect and disconnect the sources of electric current in the distribution network, characterized because the apparatus includes digital logic circuits, electronic, to excite the signal generators in response to changes in the electrical parameters detected by the detectors, circuits to program the logic for the automatic control of gener signal adores, to selectively produce any of a predetermined group of combinations of output signals in response to a predetermined group of electrical parameters in the electric current sources.
