Insulation

The dielectric is perhaps one of the most referenced tests when examining wires. The reason is that it tests the most important part of the wire insulation: determine if the wire insulation is free of breaches (or has been sufficiently degraded such that a high voltage would breach any weak points in the insulation). The basics of the test are that the entire wire, except for an inch at both ends, is placed in a water bath (with salt and wetting agent) and a high voltage potential is placed between the conductor and the return electrode in the water bath. If there is a failure in the insulation, then there will be a noticeable current flow. Dependent on the test method used, the pretest soak time, voltage amplitude and type (AC or DC) will vary.
