Abstract
A device for monitoring the properties of an electrical grid including an electrical connector for coupling to the electrical grid through a wall socket, a detector for detecting at least one property of electricity provided by the electrical grid, a receiver for receiving clock signals, and a sampler for sampling a respective detected property and recording sampled values in a memory, wherein the variation of the values with time represents a waveform of the respective property and the sampler samples at a rate sufficient to record variations of the property within a period of the waveform, wherein the device associates at least a portion of the sampled values with at least one clock signal.

A device for monitoring the properties of an electrical grid comprising:
- an electrical connector for coupling to the electrical grid through a wall socket;
- a detector for detecting at least one property of electricity provided by the electrical grid;
- a receiver for receiving clock signals;
- and
- a sampler for sampling a respective detected property and recording sampled values in a memory, wherein the variation of the values with time represents a waveform of the respective property and the sampler samples at a rate sufficient to record variations of the property within a period of the waveform,
- wherein the device associates at least a portion of the sampled values with at least one clock signal.
A system for monitoring an electrical grid comprising:
- a plurality of portable devices configured to connect to a plurality of respective wall sockets connected to an electrical grid, wherein each of the plurality of portable devices comprises:
- an electrical connector for coupling to the electrical grid through a wall socket;
