摘要
Expressions for the voltage generated by tribocharging between a cable's dielectric and outer conductor, and the maximum voltage across a resistive load of a cable, are derived as a function of time. For a reasonably large load resistance and cable capacitance, the expressions reduce to simple single-time-constant equations that can be used to estimate the highest frequency of interest of the generated noise. The derived expressions can also assist the designer in weighing the tradeoffs associated with changing the ohmic resistance and capacitance of low-noise cables. (C) 2007 Elsevier B.V.
