Abstract :
Rogowski current transducers have many features, which give them an obvious advantage over conventional current transformers in relay protection and measurement. In this article, the details of a Rogowski transducer design for application in 110 kV transformers are presented. The basic principles, system structure, and operating characteristics are introduced. The experimental results are also given.
