Analog Devices is offering a polyphase analog front end (AFE) with power quality analysis. The ADE9000 AFE features high-performance analog-to-digital converters (ADCs) in single device. Factories, hospitals, commercial buildings and other such buildings are susceptible to power supply interruption due to disturbances and variations in the power supply which is known as electricity power pollution, basically. So, the pollution in the power supply can go undetected before spoiling the expensive equipment. Basically, this chip enables to monitor such pollution in the power supply and analyze to prevent any disruptions and long-term damage to the three-phase equipment particularly for the three-phase power meters. The ADE9000 AFE integrates seven ADCs, a reference, a flexible digital signal processing (DSP) core, and proprietary algorithms into a single convenient device to deliver accurate measurements. Pre-programmed proprietary power quality software provides real-time monitoring and harmonic analysis, including magnitude and phase information. For power system meter designers who do not require the advanced power quality features of the ADE9000, the ADE9078 energy metering AFE is available for polyphase utility grade meter applications.
