摘要
提出一种通过外部有源补偿,提高TA准确度的方法。它采用磁平衡的原理,具有自动跟踪补偿的特性。通过补偿可将TA的准确度等级提高10倍,同时这种方法具有接线简单,补偿电流范围宽等特点。
An external active compensation method of TA was set forth, for enhancing accuracy. The balance of magnetic force was applied, the method has the characteristics of automatic following compensation. The accuracy of TA was enhanced by 10 times after compensation. This method has the characteristics of simple wiring and wide range compensation current.
