w Cx，其中Cx包括試品電容和附加電容（F）。（3）容量。根據(jù)試驗(yàn)變壓器輸出的額定電流及額定電壓，便可確定試驗(yàn)變壓器的容量，即P=UnIn。根據(jù)部頒標(biāo)準(zhǔn)規(guī)定，我國(guó)試驗(yàn)變壓器的電壓等級(jí)有：5、10、25、35、50、100、150、300kV等；容量等級(jí)有：3、5、10、25、50、100、150、200kVA等。由計(jì)算結(jié)果，查部頒標(biāo)準(zhǔn)即可選出所需要的試驗(yàn)變壓器。如有特殊要求，一般可向制造廠商訂購(gòu)特殊規(guī)格的試驗(yàn)變壓器。廣州變壓器檢測(cè)設(shè)備</p><p
