First Claim
1. A computer-implemented method implemented in a data processing apparatus, the method comprising:
- for a power customer location that receives power from a power source, the power customer location including a plurality of electrical loads;
receiving by a data processing apparatus and during a reporting time period, reporting data from each of a plurality of power management devices, each power management device coupled to a respective one of the electrical loads and providing power management for the electrical load;
wherein for each power management device the reporting data includes;
power characteristics as detected at the electrical load; and
a time at which the power characteristics were detected;
determining, by the data processing apparatus, from the reporting data and for each electrical load to which a power management device is coupled, a sensitivity profile for the electrical load that characterizes the ability of the electrical load to maintain a healthy state in the event of input power to the electrical load deviating from a nominal specification, the determining comprising;
determining, for each of a plurality of power characteristics, each at corresponding times, an operational state of the electrical load at the corresponding time, wherein the operational states include a healthy state during which the electrical load is not experiencing a malfunction, and a malfunction state during which the electrical load is experiencing a malfunction;
determining from the operational states at the corresponding times, transitions from a healthy state to a malfunction state and a set of power characteristics at corresponding times for the transitions, the corresponding times for each transition including corresponding times before the transition and corresponding times after the transition;
determining, for each transition from a healthy state to a malfunction state, whether the power characteristics in the set of power characteristics are indicative of a cause of the transition; and
determining the sensitivity profile based on the power characteristics that are indicative of causes of the transitions; and
generating, by the data processing apparatus, for each power management device of two or more power management devices, a load-specific protection specification for the power management device based on the sensitivity profile of the electrical load that is coupled to the power management device, wherein the load-specific protection specification is different from a load-specific protection specification for another power management device.

Abstract
Methods, systems, and apparatus for collect historical power consumption data and power consumption statistics for one or more locations and devices at the location to generate historical power consumption and health data (“historical data”). The historical data are used to develop and provide multiple different protection and monitoring functions. The system may be deployed within a single customer location, e.g., within a building or a plant, and local analytics are developed at the location. Alternatively, the system may be distributed among several locations for a particular customer or multiple different customers and include cloud-based analytics in addition to, or instead of, local analytics.
