    Inductance coil calculation on A.C., 50 Hz

    I used FEM for calculation inductance coils with core in A.C. at 50 Hz. I do not understand why inductance is written in the form of Flux/Current = A-I*B Henries. Why I? I need the magnetization curve for 230-450W steel. Does anyone know where I can find it?

    Current transformer connection

    Thank you. The current transformers are used for motor protection.

    Current transformer connection

    Thank you for your answer. The U2, V2, W2 are the ends of windings terminals of stator (not shown on image attached). In series with every phase is introduced a current transformer with P1 and P2 terminals. The star for stator winding is realized on current transformers.

    Current transformer connection

    We have three current transformers to protect an asynchronous motor. We connected the ends of the three phases of the engine to the terminals P2 and realized the star to the terminals P1. Does it matter that we didn't connect to P1? Of course it will take into account the meaning of the...
