Breakthrough voltage
Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. It is named after Friedrich Paschen who discovered it empirically in 1889. Paschen studied the breakdown … See more Early vacuum experimenters found a rather surprising behavior. An arc would sometimes take place in a long irregular path rather than at the minimal distance between the electrodes. For example, in air, at a pressure of … See more Basics To calculate the breakthrough voltage, a homogeneous electrical field is assumed. This is the case in a parallel-plate capacitor setup. The electrodes may have the distance $${\displaystyle d}$$. The cathode is located … See more Different gases will have different mean free paths for molecules and electrons. This is because different molecules have different diameters. … See more • Electrical breakdown limits for MEMS • High Voltage Experimenter's Handbook Archived 2011-10-16 at the Wayback Machine See more The mean free path of a molecule in a gas is the average distance between its collision with other molecules. This is inversely proportional to the pressure of the gas, given constant temperature. In air at STP the mean free path of molecules is about 96 nm. Since … See more Paschen's law requires that: • There are already free electrons at the cathode ($${\displaystyle \Gamma _{e}(x=0)\neq 0}$$) which can be accelerated to trigger impact ionization. Such so-called seed electrons can be created by … See more • Atmospheric pressure • Breakdown voltage • Dielectric strength • Townsend discharge See more WebBreakthrough occurs when adsorbate reaches the end of the column and leaves with the column effluent. Breakthrough curves are plots of the adsorbate concentration in the column effluent as a function of time. In the breakthrough curves shown here, mass transfer is slower for Curve 1 than Curve 2. Curve 3 is the ideal breakthrough curve, where
