    • The invention relates to a method for protecting a multi-phase autotransformer for an aircraft, including the steps of receiving (100) values of current output from (Ia, Ib) the first and second phases and a value of current input into (IB) the second phase; determining (101), from these received values of the second phase, a value of current representative of the operation (IFb) of the second phase; determining (102), as a function of this determined value and of the value of current output from (Ia) the first phase, a value representative of the homopolar current (Idet-a) flowing in the first phase; comparing (104) this value of homopolar current (Idet-a) with a first predetermined threshold value (S1) at least during a first predetermined period (D1); and controlling (106) the values of currents input into (IA, IB) and/or output from (Ia, Ib) the phases as a function of the said first comparison.
    • 本发明涉及一种用于保护飞机的多相自耦变压器的方法,包括以下步骤:从(Ia,Ib)第一和第二相接收(100)电流输出的值,以及输入到(IB)的电流值, 第二阶段 从所述第二相的接收值确定(101)表示所述第二相的操作(IFb)的电流值; 根据该确定值和来自(Ia)第一相的电流输出值的函数确定(102)表示在第一相中流动的单极电流(Idet-a)的值; 至少在第一预定时段(D1)期间将(104)该单极电流值(Idet-a)与第一预定阈值(S1)进行比较(104)。 以及控制(106)作为所述第一比较的函数的输入到(IA,IB)和/或从(Ia,Ib)相输出的电流值(106)。
