  • 什么是励磁涌流?

    What is an inrush current?

    When the transformer is connected to the power supply of rated voltage and rated frequency, the asymmetrical closing no-load current in the transition process between the no-load transformer closings is called the inrush current. The action time is very short, and it gradually decays to the steady-state no-load current , The peak value of the inrush current decays according to the exponential curve, which ... [Learn more]
