Title: Error of Current Transformers with a Half-Wave Rectified Primary Current with an Active-Inductive Load
Keywords: current error, current transformers, half-wave rectified priAbstract: In many applications of the current transformers there is a requirement for operating with a half-wave rectified primary current. The specific features characterizing the operating regime of these current transformers under the conditions considered are a result of the large direct-current component in the primary current, generated when it is rectified as a half wave. The purpose of the present work is to define the current error of current transformers with a half-wave rectified primary current at different active-inductive loads. The analysis is performed by using the software product PSpice. References - IEC 687/92; IEC 1036/90; IEC 145/63; BDS 17371-95
