Method and system for controlling a selected electrical load in a building
First Claim
1. In a system including a plurality of energy dissipating loads a method for controlling from a location remote from a load of said plurality of loads the amount of electrical energy applied to said load wherein load control information is transmitted between said remote location and said load by way of a plurality of electrical energy transmission lines including a neutral conductor, a ground conductor and a line conductor, comprising the steps of:
- (a) determining load control information representative of said energy applied to said load;
(b) applying said load control information to said energy transmission lines at an impressing end of said energy transmission lines for transmission to a receiving end of said energy transmission lines wherein said load control information is impressed between said neutral conductor and said ground conductor of said energy transmission lines to provide impressed load control information;
(c) receiving said impressed load control information at said receiving end of said energy transmission lines by obtaining said load control information from between said neutral conductor and said ground conductor to provide received load control information; and
(d) controlling said energy of said load in accordance with said received load control information.

Abstract
Energy dissipating loads are controlled from a location remote from the load. Load control information is transmitted between the remote location and the load by way of electrical energy transmission lines including a neutral conductor, a ground conductor and a line conductor. Load control information representative of the electrical energy applied to the load is determined and the load control information and applied to the energy transmission lines at an impressing end for transmission to a receiving end wherein the load control information is impressed between the neutral conductor and the ground conductor to provide impressed load control information. The impressed load control information is received at the receiving end by obtaining the load control information from between the neutral conductor and the ground conductor to provide received load control information. The energy of the load is controlled in accordance with the received load control information.

21. A system for controlling from a location which is remote from a load the amount of electrical energy from a service entrance applied to said load wherein energy control information is transmitted between said remote location and said load by way of a plurality of electrical energy transmission lines including a neutral conductor, a ground conductor and a line conductor, comprising:
-
(a) a first control signal transmission point of said energy transmission lines for impressing said load control information upon said energy transmission lines to provide impressed load control information;
(b) a tuned current transformer applied to said energy transmission lines between said service entrance and said first control signal transmission point for adjusting the impedance of said energy transmission lines;
(c) a second control signal transmission point of said energy transmission lines for obtaining said load control information from said energy transmission lines to provide received load control information; and
(d) a responder for controlling said energy of said load in accordance with said received load control information. - View Dependent Claims (22, 23, 24, 25, 26)
