Energy metering IC provides high accuracy harmonic analysis for power quality monitoring
September 15, 2011 // Paul Buckley
Analog Devices, Inc., has introduced an energy metering IC (integrated circuit) that offers real-time harmonic analysis for energy meters and power quality monitoring equipment. Designed for polyphase meters, the ADE7880 energy metering IC offers complete harmonic analysis, including magnitude and phase information, and delivers better than one percent accuracy over a dynamic range of 2000:1 up to the 63 rd harmonic.
The new device is the first to use ADI’s proprietary ARTM (adaptive real-time monitoring) harmonic analysis technology, which eliminates the need for custom development of sophisticated digital signal processing and reduces the demands on the system microcontroller.
The ADE7880 Energy Metering IC is pin compatible with the popular ADE78xx high-accuracy energy metering IC devices designed for three-phase configurations. ARTM automatically tracks changes in the fundamental frequency, which eliminates any effects of frequency drift on accuracy of the measurements.
For each harmonic, the device computes the voltage and current rms, power factor, and active, reactive and apparent powers. The IC also computes THD+N (total harmonic distortion plus noise) ratio as well as harmonic distortion as a ratio of the fundamental.
The IC delivers active and reactive energy accuracy better than 0.2% over a dynamic range of 5000:1. Accuracy better than 0.1% is achieved over a dynamic range of 1000:1 with gain calibration only.
The device incorporates seven sigma-delta ADCs (analog-to-digital converters), a digital integrator, voltage reference and all metrology signal processing. Suitable for class 0.2 meters.
The ADE7880 energy metering IC is available now packaged in a 40-lead LFCSP and is priced $9.47 each in 1,000 quantities.
