Di-Eletric Breakdown Voltage

Home Petroleum Testing Products Di-Electric Breakdown Voltage

Test Method

The dielectric breakdown voltage of an insulating liquid is of importance as a measure of the liquid's ability to withstand electric stress without failure. The dielectric breakdown voltage serves to indicate the presence of contaminating agents such as water, dirt, cellulosic fibers, or conducting particles in the liquid, one or more of which may be present in significant concentrations when low breakdown voltages are obtained.

Standard: - This apparatus conforms to ASTM D1816 and other similar test methods..
