The Influence of Electrostatic Charge on the Stability of Electronic and Electrical Equipment

Resumo

In discharge of static electricity caused by friction, the voltage can reach 25 kV and the discharge current can reach up to tens of amperes with a rise time from fractions of nanoseconds. Electrostatic discharge can lead to malfunctions of electronic equipment or even to its being damaged. The regulations require checking the operation of electronic equipment under the influence of electrostatic discharges. Tests for resistance to such discharges can be performed using specially developed test generators (simulators) of electrostatic discharges. During the tests, the influence of discharge, the parameters of which are regulated in accordance with the basic standards for test methods, is simulated. At the design stage of electronic equipment, it is proposed to use the model of electrostatic discharge simulator to evaluate the expected voltages on the equipment case and its components for prediction of test results.
