style="text-indent:25px">通過測量負載損耗的阻抗電壓和短路損耗，可以確定變壓器的并列運行條件，計算變壓器的效率，熱穩(wěn)定和動穩(wěn)定，計算變壓器二次側(cè)的電壓變動率和確定變壓器的溫升效應(yīng)，也可以發(fā)現(xiàn)變壓器屏蔽，壓環(huán)或者油箱壁中由于漏磁通所引起的附加損耗，變壓器內(nèi)部幾何尺寸改變等等，這些都可以通過變壓器的負載損耗反應(yīng)，其中的作用就非常明顯了。負載試驗時一定要將變壓器的高壓側(cè)短接，短接時盡量用**的短接線或者同規(guī)格的大電流導(dǎo)線，壓緊并接；測量負載損耗并不能發(fā)現(xiàn)鐵芯局部硅鋼片短路；鐵芯的損耗應(yīng)該采用空載試驗進行測量。</p><p
