出處：黃銘-電工機械總複習 http://miupix.cc/pm-NNEI0F 練習8想法：5Kx1/5K+2pi=80% 2pi=總損失這樣是對的嗎？ 我不曉得這題給短路試驗的用意 懇請解惑 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 221.120.66.130

推 cc281399:5KVA*0.8=4KVA ;4KVA/200V=20A ; 20*20=400A*1歐姆=400W 10/25 20:30

→ cc281399:銅損=400W; 鐵損=400W 所以損失800W 10/25 20:31

→ cc281399:大部份參考書都是5KVA/200V=25A 25A*0.8=20A 20^2*1=400W 10/25 20:33

→ king5027:原來是這樣，一開始題目就沒看懂，謝謝 10/25 20:39
