相位差测量 两同周期正弦电量对应点间角度差值的测量。此两正弦电量可以同为电压、电流，或一为电压、一为电流等。对应点常取正弦电量由负到正的过零点，相当于正弦电量函数的初相角。相位差的单位是度或弧度，正、负号表示领先或滞后关系。 待测相位差的正弦电量的频率范围很广，因此采用的测量方法和仪器一般随频率的高低来选择。常用的方法是直接法和间接法。 直接法 使用专用的仪表如指针式相位表、数字相位表，或采用阴级示波器来测量相位差。采用阴极示波器时，将两同频正弦电压信号分别加到示波器的X、Y轴，得到如图1所示的椭圆图形,则两正弦电压之间的相位差∮＝arc sin(b/α)。这一方法不能判断两信号哪一个领先或滞后，并且在∮值接近零时，椭圆也退化接近成为一条直线，即b值很小,所以∮值很难测准。 间接法 通常采用三电压表法。一般要求两电压信号有一公共点（设为a点），当分别测出两信号电压Uab、Uca,以及两电压的差值Ubc后,可画出如图2所示的电压三角形。按余弦定理，两信号电压间的相位差当∮很小时,可将Uab或Uca中较大的一个信号电压分压，使分压后两信号的数值相等。如此,在测得Uab(=Uca)及Ubc后，即可得到 (弧度)
