<p>In the system disclosed, main lines feed a plurality of respective secondary lines. Each of the secondary lines is divided into two branch lines. Within each secondary line, each branch line energizes a different type of load. An output limiter connected into the first branch line limits the output of the first branch line to a predetermined maximum value. An output regulator connected into the second branch line regulates the output of the second branch line so that the total output does not drop below a predetermined minimum value in the secondary line. A voltmeter responding to the terminal voltage of the secondary line forms a control signal for the output of the regulator. In this way, if the first branch line is loaded with household appliances, and the second branch line is loaded with household heating equipment, the output of the first branch line can be kept within the predetermined maximum value and the output of the second branch line can be maintained above or at a minimum permissible terminal voltage.</p> |
