Abstract :
The design concepts for 735-kV current transformers are illustrated. The advantages of cascade construction are elaborated. Construction and test data covering the design and manufacture of a 4-stage cascade current transformer (CT) are included. Conclusions indicate that cascade construction is the best choice for certain applications.
