- ADI's energy metering IC provides 0.1% accuracy for active and reactive energy measurement.

　　Beijing, December 10, 2009/PRNewswire Asia/ - Analog Devices, Inc. (http://www.analog.com/ ), the world’s leading supplier of high-performance signal processing solutions, has launched four new models High-precision energy metering IC - ADE7878 (http://www.analog.com/zh/ADE7878 ), ADE7868 (http://www.analog.com/zh/ADE7868 ), ADE7858 (http://www.analog .com/zh/ADE7858) and ADE7854, which can be used to improve the accuracy and performance of commercial, industrial and residential smart meters (http://en.wikipedia.org/wiki/Smart_meter). Smart meters can accurately measure the amount of electricity consumed or generated, and communicate with local power departments to achieve energy monitoring, billing and other functions. ADI's latest energy metering IC can be used to develop smart meters, improve user billing accuracy for power companies, achieve more advanced power quality monitoring, and reduce operating costs.

　　"ADI is very pleased to provide our customers with the best energy measurement technology," said Ronn Kliger, director of ADI's energy department. The accuracy and dynamic range exceed the requirements of the Class 0.2 specification of the electric energy meter industry. These four new devices can also measure reactive and active power at the same time with 0.1% accuracy, which is the first in the industry. In addition, one of the products (http:/ /www.analog.com/zh/ade7878) It also has a fundamental wave power measurement function, which is very important for power quality monitoring."

　　ADI has recently established a dedicated energy department led by Ronn Kliger to meet the growing technical demands for electric energy metering, substation automation and some emerging applications, such as solar/wind power generation, energy storage, and so on. "As a key supplier of power grid equipment manufacturers, ADI deeply understands the needs of customers," Kliger said, "We provide support to customers around the world, and they are constantly upgrading their products to adapt to emerging smart grid system development trends. ADI clearly knows that smart grids are far more complex than simple smart meters. We can provide solutions covering the entire power generation, transmission and distribution chain. In addition to innovative energy metering ICs, ADI also provides radio frequency, power line carrier communications, and power supplies. Management and digital signal processing products to fully support smart grid applications."

　　Some analysts pointed out that in the next 5 years, with the growth of smart grid deployment, the number of smart meters installed worldwide will reach 200 million. In China, the US$596 billion economic stimulus plan related to smart grids is in the process of being implemented, and it is expected that 170 million smart meters will be deployed in the next 3 to 5 years. Part of the US government's funding for upgrading the country's power grid is used to enable 13% of American households (18 million households) to install smart meters within the next three years. In Europe, Italy and Sweden have completed the deployment of advanced metering infrastructure (AMI), replacing all ordinary electric meters with smart meters. France, Spain, Germany and the United Kingdom are expected to complete AMI deployment within the next 10 years.

　　High-precision, three-phase energy metering IC

　　ADI's new ADE7878 (http://www.analog.com/zh/ADE7878), ADE7868 (http://www.analog.com/zh/ADE7868), ADE7858 (http://www.analog.com/ zh/ADE7858) and ADE7854 high-precision energy metering IC (http://www.analog.com/zh/ade7854) are designed for multi-phase configurations, including three-wire and four-wire, Y-type and delta-type. Within a dynamic range of 1000:1, they can provide 0.1% accuracy for active and reactive energy measurement, which is the first in the industry; within a dynamic range of 3000:1, they can provide 0.2% accuracy for active and reactive energy measurement. Accuracy. These new products can also provide 0.1% accuracy for current and voltage RMS measurements within a 1000:1 dynamic range.

　　In addition to measuring each phase and neutral energy, ADE7868 and ADE7878 can also monitor power quality parameters, such as SAG, peak value, period, angle measurement and phase sequence. Another industry initiative is that while maintaining normal operation, ADE7868 and ADE7878 have various anti-theft functions to ensure normal operation, which can reduce the time for on-site help and meter maintenance.

　　The ADE7878, ADE7868, ADE7858 and ADE7854 energy measurement ICs are now available for sampling, all in a 40-pin LFCSP package (lead frame chip scale package).
