Devices and systems for distributed power-grid monitoring
First Claim
1. 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 through the wall socket;
a receiver for receiving clock signals from a remote clock synchronization source through an antenna of the device; 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 of at least 50 kilo-samples-per-second 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.
