Determination of Secondary Time Constant for Current Transformer Dimensioning
نویسندگان
چکیده
In this paper, a study has been carried out to analyze the factors influencing the current transformer (CT) saturation factor (KS), in particular the secondary time constant (TS) of a CT. The study identifies and analyzes the optimum value for TS as this value varies. This paper also analyses and discusses the effect of TS to the KS factor in order to calculate the CT knee point voltage (VK) in dimensioning a CT. A comparison of guessed and measured value of TS is also done in this paper.

متن کاملDiscrimination of Inrush from Fault Currents in Power Transformers Based on Equivalent Instantaneous Inductance Technique Coupled with Finite Element Method
The phenomenon of magnetizing inrush is a transient condition, which occurs primarily when a transformer is energized. The magnitude of inrush current may be as high as ten times or more times of transformer rated current that causes malfunction of protection system. So, for safe running of a transformer, it is necessary to distinguish inrush current from fault currents. In this paper, an equiv...
