Experimental Investigation on the Correlation Between ESD Parameters and Coupling Voltage of Electronic Equipment

An experimental study on the Electronic Equipments were harmed by electrostatic discharge electromagnetic radiation field have been carried through. The system measuring ESD electromagnetic field is set up that is made up of electrically small pole antenna and measuring set of ESD current waveform stipulated in IEC61000-4-2. The air electrostatic discharge is investigated with the system. The correlation between the parameters of ESD current and ESD coupling voltages received by the electronic equipment is summarized according to a great deal of experiments. The results provide the objective data for the protection designs of the electronic devices against ESD.
