1、短路阻抗及負載損耗的測量，應(yīng)當(dāng)在試品的一個繞組的線端施加額定頻率，且近似正弦的電流，另一個繞組短路，各相處于同一個分接位置。測量應(yīng)在50%～100.0%額定電流下進行；為避免繞組發(fā)熱對試驗結(jié)杲產(chǎn)生明顯誤差，試驗測量應(yīng)迅速進行；同時準(zhǔn)確記錄試驗時繞組溫度。 2、短路阻抗及負載損耗的測量與空載試驗的測量線路相同，只是測量中無需進行電壓波形校正。 3、短路阻抗及負載損耗的測量接線；對于額定電流很小的試品，儀表（電壓表及瓦特表電壓線圈）和電壓互感器的吸收電流在測量電流中不可忽略時，應(yīng)將電壓取于電源。 4、短路阻抗是在額定頻率和參考溫度下，一對繞組中某一繞組端子之間的等效串聯(lián)阻抗；其百分數(shù)等于短路電壓與額定電壓之比，測量時應(yīng)以三相電流的算術(shù)平均值為準(zhǔn)。</p><p style="text-indent:25px">對于三角形聯(lián)結(jié)的繞組進行三相試驗時，如果低壓側(cè)為星形聯(lián)結(jié)，可采用測量低壓電流的方法；對于三角形聯(lián)結(jié)的繞組進行單相試驗時，單相電壓應(yīng)施加在三角形的兩個角上，試驗時的電壓應(yīng)與三相試驗時的相間電壓相同；對于星形聯(lián)結(jié)繞組，如果電源容量不足以進行上述單相試驗，而中性點可以利用且能承受相關(guān)的電流時，經(jīng)協(xié)商單相電源可施加于線端與中性點之間。短路試驗可以采用預(yù)先短路、選相合閘，也可以采用預(yù)先送電、選相短路的方法。對于單同心式繞組的變壓器采用預(yù)先短路時，為了避免zui初幾個周波中由于鐵心飽和產(chǎn)生的勵磁電流疊加在短路電流上，施加電壓的繞組應(yīng)該選距鐵心較遠的那個繞組。對于雙同心式繞組（高/低/高）和交疊式繞組的變壓器采用預(yù)先短路的方法試驗時，制造單位需與用戶協(xié)商。變壓器發(fā)生不同性質(zhì)的故障，聲音會發(fā)生變化。這時應(yīng)根據(jù)現(xiàn)場情采取措施，查找故障原因。</p><div
