Dielectric constant v.s. breakdown voltage
WebDec 2, 2009 · They will not withstand charging in reverse polarity for long, if at all. Assuming the dielectric becomes thinner while the distance between the plates decrease. … WebDielectric strength is measured as the maximum voltage required to produce a dielectric breakdown through a material. It is expressed as Volts per unit thickness. For a plastic material the dielectric strength varies from 1 to 1000 MV/m. Higher dielectric strength corresponds to better insulation properties.
