題目:三相,8極,Y接,1000KVA,4600V,同步機,Ra=0.1pu;Xs=0.6Pu,PF=1求Pmax=?
作法我已經打在網址中了!我想問作法1和作法2為何答案不同
其中一種作法是某補教老師上課教的,另一種是我自己寫的
到底是哪裡出問題了?請幫我解決這世紀難題!!!
________________________________________分隔線
其實答案A是上課講的答案B是我自己寫的
可以趁一下今天人氣再幫我看一題?
三繞組三相變壓器標么問題

題目在上,這是一題電機機械的問題,某補習班老師的上課例題(同一個老師)
當然,在某本坊間書上也有相同的例題,上課的解法跟書上也和我PO的都一樣,
但是我想問的是換標么基底,應該要代藍色框框的公式,所以代數字後應該是綠色框框,
但是解答如同紅色框框,少考慮電壓,有人知到是怎樣一回事?
