Abstract

In this study, electrical characterization of ceramic insulation coatings were evaluated by resistive, capacitance, and high voltage breakdown techniques. The insulation coatings were produced on Ag or AgMg sheathed Bi-2212 tapes and CuNb₃Sn wires by continuous, reel-to-reel sol-gel process. The coatings were then annealed at several temperatures and times. Dielectric constant and high voltage breakdown values for the insulation coatings were measured by using a capacitive technique and a high voltage breakdown-AC dielectric tester, respectively. The electrical properties of the coatings with dopant materials, number of dips, temperature and time of annealing process are presented
