Analog Devices Introduces Four Energy Metering ICs to Improve the Accuracy and Performance of Commercial, Industrial, and Residential Smart Meters
A smart meter accurately measures how much electricity is consumed or generated, and communicates with the local utility for power monitoring, billing, and other purposes. The four High Accuracy energy metering ICs (ADE7878, ADE7868, ADE7858, and ADE7854) enable smart electricity meters to deliver improved customer billing accuracy, advanced power quality monitoring, and reduced operating costs for utility companies. The devices introduced are significant in that they are able to measure total active and reactive energy with accuracy and dynamic range exceeding Class 0.2 specifications for energy meters. The four new devices are also the first in the industry to measure both reactive energy and active energy with 0.1 percent accuracy. In addition, one device also offers capabilities to measure fundamental-only energies, which is critical for power quality measurements…
