800KVA變壓器額定銅損耗約8.9KW.計(jì)算方法：估算每小時(shí)平均用電量=52000KWh/30天/8小時(shí)=216.7KWh估算每小時(shí)平均電功率=216.7KWh/1h=216.7KW估算每小時(shí)平均電流=216.7KW/（1.732*380V*0.9）=366A計(jì)算額定電流=800KW/(1.732*400V)=1155A估算銅損=（366A/1155A）*。

對(duì)測(cè)量用電流互感器除了幅值準(zhǔn)確度要求外，還有角度誤差要求。繼電保護(hù)用電流互感器的準(zhǔn)確度級(jí)要求一般沒(méi)有測(cè)量的高，但由于要求其在故障大電流時(shí)有較好的傳變特性，所以在相對(duì)誤差下有一個(gè)短路電流倍數(shù)的要求。一般用εPM表示，如5P10，其含義是在10倍互感器額定電流下的短路電流時(shí)，其誤差滿足5％的要求。
實(shí)測(cè)的伏安特性曲線與曩昔或出廠的伏安特性曲線對(duì)比，電壓不該有顯著下降。若有顯著下降，應(yīng)查看是不是存在二次繞組的匝間短路。2.電壓互感器空載勵(lì)磁特性試驗(yàn)電壓互感器空載勵(lì)磁特性試驗(yàn)接線如圖2所示?，F(xiàn)場(chǎng)試驗(yàn)時(shí)，電壓互感器高壓側(cè)開(kāi)路，低壓側(cè)通以額外電壓，讀取其空載電流及空載損耗。
