Abstract
Generally, an iron-cored instrument transformer has differences between the primary current and the secondary current transformer due to the hysteresis characteristics of the core. The errors of the instrument transformer can be removed by using a compensating algorithm. This paper describes the iron-cored electronic zero-phase current transformer(EZCT) having a compensating algorithm that removes the effects of the hysteresis characteristics of the iron-core. This product composes an iron-cored ZCT and an intelligent electronic device(IED) ported the compensating algorithm. The test results shows that the innovative new product can improve the performance of the conventional ZCT.
