Maxim Integrated Products Petaluma subsystem reference design

Utilities and infrastructure providers can now simultaneously and accurately measure distributed power grid data with Petaluma, a subsystem reference design from Maxim Integrated Products.

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 optimise their distribution automation signal chain.

Utility organisations 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 tuned to the 50 to 60 Hz signal to match power grids around the world. The simultaneous sampling of three phases is done with low power consumption in the 1 W range. Its high-speed sample rate (250 kSps 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 utilities and infrastructure providers.
