Abstract
An iron-cored voltage transformer(VT) is usually used to obtain the standard low voltage signal for protection and measurement. Generally, the iron-cored transformers have errors due to the hysteresis characteristics of the iron-core. An error compensating algorithm for iron-cored instrument transformer can improve the accuracy of conventional voltage transformers. This paper describes the iron-cored electronic voltage transformer having the error compensating algorithm. The innovative product composes an iron-cored VT and an intelligent electronic device(IED) having the error compensating algorithm. The test results of the iron-cored electronic voltage transformers in Korea Electro-technology Research Institute(KERI) are presented.
