此兩正弦電量可以同為電壓、電流，或一為電壓、一為電流等。對應(yīng)點(diǎn)常取正弦電量由負(fù)到正的過零點(diǎn)，相當(dāng)于正弦電量函數(shù)的初相角。相位差的單位是度或弧度，正、負(fù)號(hào)表示**或滯后關(guān)系。 </p> <p> 待測相位差的正弦電量的頻率范圍很廣，因此采用的測量方法和儀器一般隨頻率的高低來選擇。 </p> <p> 常用的方法： </p> <p> 直接法使用**的儀表如指針式相位表、數(shù)字相位表，或采用陰級(jí)示波器來測量相位差。采用陰極示波器時(shí)，將兩同頻正弦電壓信號(hào)分別加到示波器的X、Y軸，得到如圖1所示的橢圓圖形，則兩正弦電壓之間的相位差∮=arc sin(b/α)。這一方法不能判斷兩信號(hào)哪一個(gè)**或滯后，并且在∮值接近零時(shí)，橢圓也退化接近成為一條直線，即b值很小，所以∮值很難測準(zhǔn) </p> <p> 間接法通常采用三電壓表法。一般要求兩電壓信號(hào)有一公共點(diǎn)（設(shè)為a點(diǎn)），當(dāng)分別測出兩信號(hào)電壓Uab、Uca，以及兩電壓的差值Ubc后，可畫出電壓三角形。按余弦定理，兩信號(hào)電壓間的相位差當(dāng)∮很小時(shí)，可將Uab或Uca中較大的一個(gè)信號(hào)電壓分壓，使分壓后兩信號(hào)的數(shù)值相等。
