Fast Stability and Intelligent Algorithm Dynamic Filtering: For the large inductance characteristics of transformers, a special current rise control algorithm is adopted to make the current quickly reach a stable state. Noise suppression: In strong electromagnetic interference environments (such as in substations), it can accurately extract weak voltage signals. C. Wide Range and High Precision Range: Typically covers 1μΩ ~ 20kΩ (or even wider). Low-voltage side high-current windings: milliohm/micro-ohm level (requires high current, such as 20A-40A). High-voltage side low-current windings: ohm/kilo-ohm level (requires high sensitivity). Precision: Typical accuracy is ±0.2% or ±0.1%, with resolution up to 0.1μΩ. D. Intelligence and Data Management Automatic judgment: Built-in standard library, automatically calculates three-phase unbalance rate ( (
