| Abstract |
In the distribution networks, it is necessary to develop small and light voltage and current sensor for compact and digitalized switchgears. For this purpose, some researches have been continuing till now, CT(current transformer) and VT(voltage transformer) are one of that research. But conventional CT and VT have some problems, that is, have big size and saturation characteristics because of used to iron core. In this paper, CS(current sensor) and VS(voltage sensor), have some merits measuring of current and voltage magnitude as a alternated conventional equipment, were studied. So, this paper shows the process CS and VS design method, equivalent circuit and output result, respectively. As a result of this test, proposed CS and VS have linearity for the output, no saturation. |
