對每一種電流互感器，二次開路電壓隨著一次電流的變化，都有嚴格的對應關系，*以一次額定電流時的二次開路電壓值說明。對母線穿心式150／5的電流互感器，當穿心電流為額定值時，不同品種的電流互感器二次開路電壓為2．6～2；4V。80條二次開路電壓特性曲線的規(guī)律是：一次穿心電流從0A增至150A時，二次開路電壓開始上升幅度很大，30A以后增加甚小(即使從150A增至800A，二次開路電壓平均只上升0．2V)。 </p> <p> 母線穿心式200/5的電流互感器，二次開路電壓是3．9～6．5V；母線穿心式 300／5—2000／5的電流互感器，二次開路電壓為6．5～37．2V。 </p> <p> LQG系列從30／5—600／5的電流互感器，二次開路電壓是12．8～21．4V。 </p> <p> 變電站用的LQJ，LFC，LFCD系列50／5～300／5的電流互感器，二次開路電壓是18～121．3V。 </p> <p> 在第二次伏安特實驗臺上，利用調壓器、電流表、導線將所有的電流互感器二次線圈分別接人調壓器的輸出端，當二次輸入5A電流時，測得二次電壓和一次加額定電流時測得的二次開路電壓都有嚴格的對應關系。若用公式計算，二次開路電壓等于二次閉路轉為開路一次電壓的增量乘以變化。從正反兩方面實驗和法拉第電磁感應定律推導結論證明了二次開路電壓測試值的真實性 </p><p>

消除誤差的方法兩年內我們探索了導線、分數(shù)匝、電容、電感、電阻絲等對正比差補償方法。1995年底，我們終于找到了可使電流互感器正、負比差都明顯減小的技術方案。例如23號200／5的電流互感器，當母線穿心一匝，一次電流為180A時，二次顯示194A，正比差為14A，一次電流為5A，二次示數(shù)為0A，負比差為5A。利用這種技術方案，可以使該電流互感器一次電流從0A到額定電流的整個區(qū)間，正比差為0A，負比差額定值為lA，從而發(fā)現(xiàn)了降低電流互感器比差的技術方案。電流互感器的負載特性當二次測所接負載阻抗遠大于銘牌上標定的阻抗時，電流互感器是一恒壓源。例如9號150／5互感器，銘牌上標定的阻抗為0．2Ω。當一次電流為150A，二次開路時，用MFl73型萬用表交流10V檔，精度為9kΩ／V，相當于在二次回路上串聯(lián)90kΩ的電阻，測得其電壓為2．6V；當二次測并接15Ω300磁場變阻器，分別取阻值15Ω、7．5Ω、3．75Ω時，二次電壓仍為2．6V；當取1．875Ω時二次電壓才降為2．55V，有力地證明了上述結論。當外阻遠小于標定阻抗時，電流互感器接近一恒流源。例如9號150／5互感器，將一次電流調至135A。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
