Abstract

Elektrodenvorrichtung (1) zur kontaktlosen Beseitigung einer elektrostatischen Aufladung von einem geförderten oder einem zu fördernden elektrisch im Wesentlichen isolierenden Material mit wenigstens einer Elektrode (3), welche in einem Elektrodenprofil (2, 2a) angeordnet ist und einer Spannungszuführung (5) zur Spannungsversorgung der wenigstens einen Elektrode (3), wobei die Elektrodenvorrichtung (1) weiterhin eine Vorrichtung (14) zur Bestimmung eines Parameters, welcher in Abhängigkeit vom Oberflächenpotential auf dem geförderten oder zu fördernden Material variiert, wobei der Parameter vorzugsweise in der wenigstens einen Elektrode entsteht, sowie eine Steuervorrichtung (12) zur Steuerung einer an der wenigstens einen Elektrode (3) anliegenden Spannung und/oder eines durch die wenigstens eine Elektroden fließenden Stromes und/oder eines Tastverhältnisses und/oder einer Frequenz, mit welcher die wenigstens eine Elektrode mit gegenpoligen Spannungen versorgt oder ein- und ausgeschaltet wird, aufweist, welche die Elektrodenspannung und/oder das Tastverhältnis und/oder den Strom und/oder die Frequenz in Abhängigkeit des Parameters steuert.
