How to use AC Power Calculator

  1. 选择单相或相相相相 AC 系统 .
  2. 输入电压(V),电流(Amps),和动力因子(一般在0.1到1.0之间).
  3. 即刻读取计算出来的活性能,显性能,和活性能.

{姓名}是什么来着?

取代电流(AC)电路携带活性电能(W),表面电能(VA)和活性电能(VAR). 在单相电路中,活性能P = V × I × PF. 在平衡的三相电路中,活性能P = √3 × V 行× I × PF. 电源系数(PF)代表电压和电流之间的相相角。

FAQ

什么是权力因素?
电能因子(PF)是电路中流出的实际电能(W)与表面电能(VA)之比,衡量电能如何被有效转换为有用的活.
单相能与相相能有何区别?
单相电能使用活导电器,常见于住宅. 三相电能使用三台活导电机,为工业机械和商业建筑提供更平滑更一致的供电.
