- Abstract:
- A detailed analysis of the crosstalk in the gapped-core current sensor is presented in this paper. The gapped-core current transducer with a magnetic field sensor in the airgap is widely used to measure current in industries and laboratories. We examine the effect of a nearby current-carrying conductor on the performance of the gapped-core transducer, for the first time in this paper. The crosstalk is studied by considering various factors such as angular and linear displacement of the external conductor, core material, and position of the main conductor. A 3D Finite Element Method (FEM) based model is used to analyse the cross talk and results are presented in this paper. This analysis helps the designer to get detailed insight into the effect of the external conductor on the gapped core current transducer.
