Advanced Turn Ratio Testing for Special Transformers: Scott, Inverse Scott, and V-v Connections

Four Fast 1 Error Analysis of Traditional Turn Ratio Testing MethodsThe QJ35 turn ratio bridge and other single-phase-phase-based testers all use the double-voltmeter principle. The QJ35, however, eliminates power supply fluctuation interference via bridge balance. For three-phase transformer ratio testing with a single power supply, corresponding terminals must be shorted and data converted, turning three-phase tests into independent single-phase measurements, with √3 Yd conversion based on con
