March 1, 2007 -- Besieged by conservation issues, utility metering is undergoing somewhat of a renaissance—particularly electricity metering. That's because electrical distribution systems everywhere are fragile. Metering used to be the nearly exclusive domain of EEs with a power specialty. Today, it's wide open to chip, board, and system designers, as well as software writers.
The reluctance-motor electrical-meter movement is more than 100 years old. Now, it's getting displaced by chips that aren't just cheaper and more precise, but also can separate the active and reactive components of power and provide gateways to remote reading.
