  • Powerline pulse position modulated three-phase transmitter apparatus and method
    Patent number: 9293918
    Abstract: An electrical control system consisting of two or more electrical transmitting devices each capable of transmitting synchronized messages consisting of electrical pulses to devices connected to one or more of the three phases of the AC power lines in a typical three phase power system. The synchronized transmitters are each connected to neutral and to one or more of the three phases, A, B, and C, or across two of the phases, of different circuit breaker panels in a typical three phase power system, and are capable of transmitting messages to one or more of the three phases. The transmissions from the two or more transmitters are synchronized such that the transmitted pulses from each transmitter are transmitted at the same time to produce a message that can be received correctly at any receiving device connected to any of the connected circuit breaker panels.
