Measurement of the magnetic field radiating by electrostatic discharge generators along various directions

The aim of this paper is to investigate the transient magnetic field radiating by electrostatic discharge (ESD) generators. Near field measurements have been conducted, a few centimeters far away from the discharge point (Pellegrini target). The Pellegrini target is mounted on the centre of a grounded metal plane, inside an anechoic chamber. The measurements were carried out to three different directions in relation to the discharge point. The experimental data show that each ESD generator produces a different transient magnetic field. Furthermore, additional differences referring to the produced magnetic field produced by each generator are noted, depending on the direction that the measurement is conducted. Finally, comparisons are stated concerning the magnetic field produced by each generator as well as useful conclusions for the decrease of the magnetic field
