3 Terms and units of measurement

3.1 Inductive coil A conductor ring with a certain shape and size, when current flows through the ring, it is generated in its plane and the enclosed space Definite magnetic field. 3.2 Inductive coil factor The ratio of the magnetic field strength generated by the induction coil of a certain size to the corresponding current. In the case of equipment, measured at the center of the coil plane. 3.3 Standard induction coil standardinductivecoil Induction coil with 1 turn and size of 1m × 1m or 1m × 2.6m.

4 Overview

The power frequency magnetic field simulator is generally composed of a power frequency current generator and an induction coil. Among them, the main frequency current generator It should be composed of voltage regulator, control loop and current transformer; the induction coil is made of copper, aluminum or other conductive non-magnetic materials Material. The power frequency magnetic field simulator is mainly used to simulate the influence of the magnetic field generated by the power frequency current on the equipment under operating conditions. Check the ability of the tested electronic equipment to resist power frequency magnetic fields. ......
