Özet
The instantaneous currents must be measured precisely and accurately in order to monitor electrical circuits under different operating conditions. Rogowski Coils (RC) can be easily connected even in narrow spaces where the measuring device cannot enter. They perform current measurement using the secondary voltages produced at a few mV levels even at the nominal currents (3000 - 60000 A). Therefore, it is difficult to make measurements with RCs, especially at low current values such as a few ten amperes, and the results are prone to the measurement errors. In order to increase the measurement sensitivity without changing the physical dimensions of the RC, a magnetic-core structure can be preferred instead of an air-core. In this paper, the magnetic filaments have been produced using nickel alloys at different ratios (40% and 60%). Flexible magnetic-core RCs have been developed by winding the magnetic filaments. Considering the flexibility of the core, the magnetic filaments have been produced in two different alloy ratios. The relative permeabilities of the developed magnetic filaments have been determined by experimental studies and their linear characteristics in the range of 5-400 A have been verified by finite element analysis.
