Skin effect, английский
- The tendency of alternating current to travel only on the surface of a conductor as its frequency increases.
- Phenomenon wherein the depth of penetration of electrical currents into a conductor decreases as the frequency of the current is increased. at very high frequencies, the current flow is restricted to an extremely thin outer layer of the conductor. see standard depth of penetration.
- Term used to describe the penetration ability of cyclical current or magnetization as a function of frequency, conductivity and relative permeability. in magnetic particle testing, skin effect refers to alternating current’s inability to penetrate deeper than 1 to 3 mm (0.04 to 0.12 in.) with typical testing variables.10
- Skin depth.
