A new modeling of inductive sensors for current measuring at high voltage

Inductive sensors are used in electric equipment like current measuring insulators and metal detectors. Modeling of these sensors will raise their accuracy and consequently will lead to developing of high precision current measuring devices. The idea of expressing the voltage induced in the sensor in terms of current passing through the line and geometrical parameters is the goal of this study. Inductive sensors with rectangular cross section have been studied and the results show good conformity with previous works Changes in dimensions like varying the diameter of current carrying cable will cause big error in current sensing if the modeling is not considered.
