摘要
文章分析了二次绕组带有抽头的套管电流互感器 (CT) ,其二次端子接线错误对CT变比的影响。指出在实际工作当中应当正确理解“CT二次线圈严禁开路”所指含义 ,灵活应用 。
The paper analyses the current transformer(CT) that secondary winding possesses casing tap,and its secondary connector wiring fault's influence on the CT changing rate.Also the paper indicates the exact meaning of `prohibiting the secondary wiring broken-circuit',and applies it flexibly in order to ensure the protecting equipment's safe action
