Abstract
A device, system, and a computer-implemented method a for identifying an anomaly in an operation of a device includes comparing, by an electrical power analyzer, a current power draw signature of the device with a known power draw signature of the device. There is a determining as to whether at least one anomaly is present in the current power draw signature. A warning is generated in response to determining the at least one anomaly is present in the current power draw signature.

A computer-implemented method of identifying an anomaly in an operation of a device, comprising:
- measuring voltages of lead pairs connected to respective prongs of an electrical plug;
- determining, based on the measurement, a current power draw signature of the device based on an analog waveform data stream of the device;
- digitizing the analog waveform data stream;
- comparing, by an electrical power analyzer coupled to an electrical outlet, the current power draw signature of the device with a known power draw signature of the device;
- determining whether at least one anomaly is present in the current power draw signature indicating an imminent failure of the device;
- and
- generating a warning in response to determining the at least one anomaly is present in the current power draw signature.
An electrical power analyzer, comprising:
- a voltage measurement module configured to measure voltages of lead pairs connected to respective prongs of an electrical plug and to output analog waveform data streams of a device;
- a sampler and digitizer configured to generate a current power draw signature of the device based on received analog waveform data streams output from the voltage measurement module, and to digitize the analog waveform data streams;
- a memory configured to store the digitized waveform streams;
- and
- a communications module including a buffer, the communications module configured to receive and output the digitized waveform data streams;
- and
- a processor configured to compare the current power draw signature of the digitized waveform streams received from the communications module with a known power draw signature of the device, and to generate a warning in response to a determination that the waveform data streams include at least one of an anomaly or artifact.
An electrical power system for environmental and ecological optimization, the system comprising:
- an electrical power analyzer configured for insertion into a branch electrical outlet, the electrical power analyzer including at least three prongs with at least three separate analytical leads forming at least three lead pairs, and an input receptacle configured to be electrically connectable to a power cord from a device being monitored;
- a data acquisition module including an operational amplifier configured to measure a voltage of each of the three lead pairs;
- a sampler and digitizer configured to sample analog waveform data streams output from the data acquisition module and output a power draw signature of the digitized waveform data streams;
- and
- a communications module configured to record and transmit the power draw signature of the digitized waveform streams to an analysis module and to transmit a warning based on analysis of the power drawer signature performed by the analysis module;
- wherein the communications module is further configured to transmit a warning based on information received from the analysis module about an operational status of the device;
- and
- wherein the received information includes a potential failure risk of the device being monitored and recommended corrective action associated with the device being monitored.
