ABSTRACT:
Inductive current sensor and electrical apparatus incorporating this sensor. The magnetic circuit of the sensor comprises a separable part carrying the detector element and is made of a material having a permeability lying between 5 and 100. The circuit reduces the influence of spurious gaps and external interference on the current sensor for the electrical apparatus.
