1. A power distribution system including load tap changing transformers and associated conventional voltage maintenance circuits, comprising:

  • substation controller means, associated with each load tap changing transformer, for responding to overide and control signals input thereto to override normal tap changing operation of said voltage maintenance circuits, and for subsequently and selectively controlling the tap position of said tap changing transformer to produce step changes in the line voltage output of said tap changing transformer to thereby produce an encoded message;

    central station controller means for inputting said override and control signals to said substation controller means; and

    ,a plurality of load control receiver means for monitoring said step line voltage changes caused by said load tap changing transformer and, in response to said encoded message, selectively interrupting power to loads which are uniquely associated with each of said plurality of receiver means.
