Dependence and Its Calculation on Breakdown Potential Gradients of Air Discharge Current Peaks from ESD Generator in Environment with Different Temperature and Humidity

Abstract

The air discharge currents from an ESD generator were measured at charging voltages from 2 kV to 15 kV in an environment with different temperature and humidity. Dependence of the current peaks on breakdown potential gradients in addition to spark lengths is shown, and is calculated using a simplified equivalent circuit based on the IEC standard for the ESD generator.
