디지탈 제어용 CT의 국제규격(IEC 60044-8)에 대한 검토

A Study about International Standard of Digital Controlled CT

Conventional current transformers possess many qualities due their simplicity. However, the technological innovations now underway in the field of switchgear and substation control systems tends to underline their drawbacks. New technologies must be developed to provide users with better service quality in terms of precision, operating safety and interoperability. The current transformer presented combines simplicity and the high degree of precision offered by Rogowski coils with the processing possibilities of digital electronics.
