| Abstract(in English) | International Electrotechnical Commission (IEC) prescribes immunity tests (IEC61000-4-2) of electronic equipment against electrostatic discharge (ESDs), and specifies indirect discharges of an ESD-gun onto vertical coupling plane (VCP) in the vicinity of equipment under test (EUT) for simulating personal discharges to conductive materials being adjacent to the EUT. According to IEC61000-4-2 2001-04, the VCP shall be placed at a distance of 0.1m from the EUT, and the indirect discharges of an ESD-gun should be conducted to the centre of a vertical edge of the VCP, while the reference arrangement of EUT is not specifically determined. In the present study, by using a magnetic field probe and a dipole antenna in lieu of EUT, we measured their induced voltages for indirect discharges of an ESD gun onto a VCP, and investigated the variability in peaks and waveform energies with respect to the positions of the probe and antenna. As a result, we found that there are some differences in the peaks and waveform energies of the induced voltages even if the ESD-gun was fixed at a specified position, while indirect discharges onto a vertical edge from the back side of a VCP are very likely to reduce the above-mentioned variability by 50% at least. |
