Hi, I used an online translator at http://free-translation.imtranslator.net/default.asp?ldr=en/ko&loc=en 有功电量 - Active Power

Like clest, I also used google but I did a search on 有功电量 which returned a number of articles in Chinese which I had translated by google. The articles were all technical and on such subjects as power transmission. I understand that in addition to Active Power (有功电量) there is also Reactive Power (无功电量) and these are components used in calculating the Power Factor (功率因数). You might compare the article at http://zhidao.baidu.com/question/33671901.html with the english translation of the web page which can be obtained using google.
