Method and apparatus for preventing overloads of power distribution networks
First Claim
1. A system for monitoring power in a power distribution system, the system comprising:
- a power monitoring device located in the power distribution system to measure a value of at least one characteristic of power provided to a branch of the power distribution system, the power monitoring device having an output that provides the value measured; and
a controller having an input to receive the value measured and an output that couples to a first device powered by the branch of the power distribution system to send a power signal to the first device to command the first device to operate at a predetermined percentage of maximum power.

Abstract
Systems and methods for monitoring power in power distribution systems are provided. In one aspect, a system for monitoring power includes a power monitoring device that measures a value of at least one characteristic of power provided to a branch of a power distribution system. The power monitoring device includes an output that provides the value measured. The system further includes a controller having an input to receive the value measured and an output that couples to a first device powered by the branch to send a maximum power signal to the first device to command the first device to operate at a percentage of maximum power.

23. A method for monitoring and controlling a power distribution system that has a plurality of circuit branches for providing power to a plurality of devices, the method comprising:
-
controlling a first device on a first circuit branch to operate at a predetermined percentage of maximum power;
detecting a first value for a characteristic of power provided to the first circuit branch;
controlling a second device on a second circuit branch to operate at a predetermined percentage of maximum power;
detecting a second value for a characteristic of power provided to the second circuit branch;
adding the first value to the second value to obtain a total value;
comparing the total value to an overload value to detect an overload condition;
indicating an alarm condition when the total value exceeds the overload value. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 48, 49)
