System For Detecting Load Loss Following An Electrical Power Disturbance
First Claim
1. A method of detecting an electrical load loss following an electrical power disturbance in a monitored electrical power distribution system, said method comprisingdetermining an expected characteristic of a parameter representing normal operation of an electrical load or power circuit receiving power from said electrical power distribution system,storing said expected characteristic of a parameter in a computer memory,measuring an actual characteristic of said parameter in said power distribution system,storing said measured actual characteristic,detecting a disturbance in said monitored electrical power distribution system, anddetermining whether said load or power circuit, or a portion of said load or power circuit, was lost as a result of said disturbance, by evaluating said actual characteristic of said parameter after termination of said disturbance with respect to said expected characteristic of said parameter and outputting from said computer the results of said determination of whether said load or power circuit, or a portion of said load or power circuit, was lost as a result of said disturbance.

Abstract
A method of detecting an electrical load loss following an electrical power disturbance in a monitored electrical power distribution system comprises (1) determining an expected characteristic of a parameter representing normal operation of an electrical load receiving power from the electrical power distribution system, (2) detecting a disturbance in the monitored electrical power distribution system, and (3) determining whether the load, or power circuit, or a portion of the load or power circuit, was lost as a result of the disturbance, by evaluating an actual characteristic of the parameter after termination of the disturbance with respect to the expected characteristic of said parameter.
