  • 变压器功率表示意思

    Meaning of transformer power

    Transformer power is expressed in a variety of ways. The active power is divided into active power (P) and reactive power (Q). The vector sum of the two is the apparent power (S), which is actually the relationship of the trigonometric function: S2 = P2 + Q2. 【Learn more】

  • 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]
