Abstract
A device intended to measure fouling and to locally heat an electrical insulating medium. At least one electrically resistive heating element (6, 8) is associated with a fouling detection unit. The fouling detection unit includes metallic elements (6, 10) in contact, at at least two points, with the insulating medium. The resistance variation between the two points is measured and is directly linked with the fouling of the medium.
