ABSTRACT:
A central station monitors the use of electrical power and when peak demand periods occur, coded information is transmitted by radio from the central station to remote receivers mouned on poles proximate power distribution transformers serving the customers. The transmitted signal includes both address and command information which are decoded at the receivers. Those receivers which have been addressed pass the command information as carrier signals over the distribution lines from the secondaries of the respective distribution transformers to the customers. This address information informs the customers of the existence of the peak load conditions and/or controls the operation of the customers' power consuming devices and electric meter.
