合理地选择和使用电气设备，用户的同步电动机可以提高功率因数，甚至可以使功率因数为负值，即进相运行。而感应电动机功率因数很低，尢其是空载和轻载运行时 ，所以应该避免感应电动机空载或轻载运行。安装并联补偿电容器或静止补偿等设备，使电路中总的无功功率减少；也可以选择大功率净化稳压器，提高用电质量和用电设备的功率因素。当直流电流通过导线时，电流在导线截面分布是均匀的，导线通过交流电流时，电流在导线截面的分布是不均匀的，中心处电流密度小，而靠近表面电流密度大，这种交流电流通过导线时趋于表面的现象叫趋表效应，也叫集肤效应。考虑到交流电的趋表效应，为了有效地节约有色金属和便于散热，发电厂的大电流母线常用空心的槽形或菱形截面母线。高压输配电线路中，利用钢芯铝线代替铝绞线，这样既节约了铝导线，又增加了导线的机械强度。
