Abstract

An apparatus includes a memory and a hardware processor communicatively coupled to the memory. The hardware processor receives, from a plurality of power supplies, a plurality of indications of electrical power disturbances detected by the plurality of power supplies and determines locations of the plurality of power supplies based on the plurality of indications. The hardware processor also determines, based on the plurality of locations, an event that caused the electrical power disturbances and classifies the event based on the location of the plurality of power supplies.

First claim

What is claimed is:

1. An apparatus comprising:
a memory; and
a hardware processor communicatively coupled to the memory, the hardware processor configured to:
receive, from a plurality of power supplies, a plurality of indications of a first electrical power disturbance and a second electrical power disturbance detected by the plurality of power supplies;
determine locations of the plurality of power supplies based on the plurality of indications;
determine times when the first electrical power disturbance and the second electrical power disturbance were detected by the plurality of power supplies based on the plurality of indications;
determine, based on the determined locations and the determines times, that the first electrical power disturbance affected a first number of devices and spread from a power switch or breaker;
in response to determining that the first electrical power disturbance affected the first number of devices and spread from the power switch or breaker, determine that the first electrical power disturbance was caused by a utility event;
determine a first remedy for the first electrical power disturbance based on the first electrical power disturbance being caused by the utility event;
determine, based on the determined locations and the determines times, that the second electrical power disturbance affected a second number of devices less than the first number;
in response to determining that the second electrical power disturbance affected the second number of devices, determine that the second electrical power disturbance was caused by a hardware failure; and
determine a second remedy different from the first remedy for the second electrical power disturbance based on the second electrical power disturbance being caused by the hardware failure.

2. The apparatus of claim 1 , wherein the hardware processor is further configured to generate a map showing the locations of the plurality of power supplies.

3. The apparatus of claim 2 , wherein the hardware processor is further configured to determine whether the utility event or the hardware failure caused the second electrical power disturbance based on the map.

4. The apparatus of claim 3 , wherein the hardware processor is further configured to communicate, in response to determining that the hardware failure caused the second electrical power disturbance, a request for servicing of a plurality of devices corresponding to plurality of power supplies.

5. The apparatus of claim 1 , wherein the plurality of indications comprises the times when the first electrical power disturbance and the second electrical power disturbance were detected by the plurality of power supplies.

6. The apparatus of claim 1 , wherein the hardware processor is further configured to examine a flag to determine whether the first electrical power disturbance occurred.
