Electrical properties of plastic and oil composite insulating structures

The object of this program is to measure the electrical properties of solid polymeric films in composite structures with oil. There are many routes one can take to evaluate electrical insulating materials for use, for example, in high-voltage-cable applications. You can build a cable and test it — a very expensive procedure — or you can wrap models using small-diameter rods and a limited number of wraps of tapes. Another approach is to use a uniform-field flat-film system using guarded electrodes. It is possible that accurate data can be obtained easily and inexpensively from measurements made in a uniform field.
