Utility organizations worldwide are deploying more robust applications that require highly accurate distributed grid status data to leverage distributed generation technologies such as solar and wind power. Voltage and current measurements must be gathered simultaneously for all lines, so the utility can understand the timing among phases and ensure maximum uptime across the grid. Petaluma is a high-speed, simultaneous-sampling, 8-channel analog input front-end (AFE) that monitors grid data simultaneously from all phases, so grid managers can optimize their distribution automation signal chain.

Petaluma is tuned to the 50Hz to 60Hz signal to match power grids around the world. The simultaneous sampling of three phases is done with low power consumption in the 1W range. Its high-speed sample rate (250ksps per channel) comes with 16-bit accuracy, allowing for quick responses to grid fault conditions. Petaluma performs well in any application that requires multiple simultaneous sampling of analog inputs, such as multiphase motor control and industrial vibration sensing, to accurately calculate instantaneous power consumption.
