摘要
The short-circuit impedances in three typical power auto-transformers are derived with the relative magnetic leakage method. The formulas for the efficiency coefficient of the three products are presented.The factors to influence the efficiency coefficient and the deviation of the short-circuit impedance between limit tap and rated tap are analyzed.
