Building Resilient Edge Data Pipelines for Power Grid Sensors

This article outlines an architecture for collecting sensor data from electrical grids, processing it at the edge to reduce bandwidth and storage costs, and ensuring fault detection remains operational during network outages. It emphasizes separating telemetry from events and using local buffers and rules to handle unreliable connectivity. The approach handles up to 18 million measurements per hour from 5,000 sensors while maintaining reliability.
