Title:
MEASUREMENT DEVICE FOR MEASURING OPERATION CURRENT AND FAULT CURRENT OF CIRCUIT BREAKER BY USING SINGLE ROGOWSKI COIL
Document Type and Number:
WIPO Patent Application WO/2023/085485
Kind Code:
A1
Abstract:
The present invention relates to a measurement device for measuring an operation current and a fault current of a circuit breaker by using a single Rogowski coil, capable of simultaneously measuring the operation current and the fault current with the single Rogowski coil, to thereby reduce an installation space and manufacturing costs, and improve reliability by satisfying the accuracy required for measurements of the operation current and the fault current at the same time. The measurement device for measuring an operation current and a fault current of a circuit breaker by using a single Rogowski coil, comprises: a Rogowski coil installed to surround a conductor in which a current flows; a protection circuit outputting a fault voltage on the basis of a voltage generated from a tap installed in part of the Rogowski coil; and a measurement circuit outputting an operation voltage on the basis of a voltage generated in the entire coil of the Rogowski coil.
