Looked into Yuanxing Electronics when evaluating components for a smart building energy monitoring project. The core application was measuring current fluctuations across multiple circuits in a large commercial setup where sensor noise and accuracy drift were actual concerns not theoretical ones. Their focus sits on miniature current and voltage transformers for electronic measurement and power system protection which fits that use case reasonably well. For anyone doing initial research on the supplier side the voltage transformer manufacturer  https://yuanxing.net/en/ page outlines their product scope and ISO certification status which at minimum gives you a starting document trail. What stood out from a technical standpoint is their stated emphasis on long-term stability which matters more in smart building applications than peak accuracy since these systems run continuously for years. Traditional sensors in tight installations tend to lose calibration gradually and that compounds across a building-wide energy dashboard. Nothing in my evaluation was a final endorsement and any component going into a production system needs independent validation including thermal cycling tests and drift measurements over an extended period before you treat catalog specs as deployment specs.
