Abstract

This paper describes the theory and practical design of Rogowski coil and active integrator. The coils and integrators have the ratings as follows. 1) current ratings between 20kArms and 200kArms 2) current duration 3 seconds 3) time constant of primary circuit looms 4) inner diameter of coil is suitable for mounting at the busbar $200mm{\times}200mm$. The actual results in the short-circuit tests and compare with other sensors, such that shunt. are given also.
