Patent ID: 7174258

Claim:
A device for measuring electrical energy in an electric circuit, said device comprising: at least one sensor coupled with said electric circuit and operative to sense at least one electrical parameter in said electric circuit and generate at least one analog signal indicative thereof; at least one analog to digital converter coupled with said at least one sensor and operative to convert said at least one analog signal to at least one digital sample; at least one time synchronization receiver operative to generate at least one time synchronization signal; a local synchronization circuit coupled with a network and with said at least one time synchronization receiver and operative to receive at least one timing clock signal over the network and generate a synchronized timing clock signal by altering said at least one timing clock signal based on at least one of said at least one time synchronization signal, and a processor coupled with said at least one analog to digital converter and said local synchronization circuit and operative to receive said synchronized timing clock signal.
