中国石油大学(华东)《电工电子学》在线作业(三)实验部分答案
四、实验内容及步骤
1．本实验采用线电压为220V的三相交流电源。测量该电源的线电压（UAB、UBC、UCA）和相电压（UAO、UBO、UCO），并记录之。
2．星形对称有中线：按图1接线，每相开3盏灯。测各线电压、各相电压、各相电流、两中点间电压UOO'，记录于表1中。
2.不对称三相电路
在三相三线制星形连接的电路中，若负载不对称，电源中点和负载中点的电位不再相等，称为中点位移，此时负载端各相电压将不对称，电流和线电压也不对称。
在三相四线制星形连接的电路中，如果中线的阻抗足够小，那么负载端各相电压基本对称，线电压也基本对称，从而可看出中线在负载不对称时起到了很重要的作用。但由于负载不对称，因此电流是不对称的三相电流，这时的中线电流将不再为零。
