计算客户功率因数时应注意什么？
参考答案：
（1）凡装有无功补偿装臵且有可能向电网倒送无功电量的客户，应随其负荷和电压变动及时投入或切除部分无功补偿设备，电业部门应在计量点加装有防倒装臵的反向无功电能表，按倒送的无功电量与实用无功电量绝对值之和，计算月平均功率因数。
（2）计费电能表未装设在产权分界点的客户，计算功率因数时应考虑线路和变压器的有功及无功损耗。
（3）总表内的居民生活电量，参加功率因数计算，但电费不参加功率因数调整。

| Night after night, she came to wrap me in, even long after my childhood years. Following her longstanding custom, she'd lean down and push my long hair out of the way, then 1 my forehead. I don't remember when it first started 2 me-her hands pushing my hair that way. But it did annoy me, for they felt work-worn and rough 3 my young skin. Finally, one night, I 4 her, "Don't do that anymore -your hands are rough!" She didn't say 5 in reply. But 6 again did my mother close out my day with that familiar 7 of her love. Time after time, with the passing years, my 8 returned to that night. By then I missed my mother's hands; 9 her goodnight kiss on my forehead. Sometimes the incident seemed very 10 ,sometimes far away. But always it hid, in the back of my mind. Well, the years have passed, and I'm not a little girl anymore. Mom is in her mid seventies, and those 11 I once thought to be so rough are still doing things for me and my family. She's been our doctor, 12 a medicine box to calm a young girl's stomach. She cooks the best fried chicken in the world...gets 13 out of blue jeans that I never could wash out... Now, my own children are grown and gone. 14 , in my memory, for the thousandth time,I 15 the night when my young voice complained, "Don't do that any more-your hands are rough!" Catching Mom's hand in hand, I blurted out (冲口而出) how 16 I was for that night. I thought she'd remember, 17 I did. But Mom didn't know what I was talking about. She had forgotten-and 18 long ago. That night, I fell asleep with a new appreciation for my 19 mother and her caring hands. And the 20 that I had carried around for so long was nowhere to be found. | ||||
