Abstract

A system for assessing one or more temperatures along an insulated conductor in an opening in a subsurface formation includes an insulated conductor with a length comprising at least two sections of insulation with different capacitances. The sections with the different capacitances include different takeoff temperatures for at least one dielectric property of the insulation.
