MISMO 153b Automatic Dieelectric Breakdown Voltage Tester As Per Astm D 877, Astm D 1816


Test Method :-

The dielectric breakdown voltage is a measure of the ability of an insulating liquid to withstand electrical stress. The power-frequency breakdown voltage of a liquid is reduced by the presence of contaminants such as cellulosic fibers, conducting particles, dirt, and water. A low result in this test method indicates the presence of significant concentrations of one or more of these contaminants in the liquid tested.

Standard :-

Conforms to: ASTM d877; ASTM D 1816, ip-295.

Features & Benefits :-

This test method is used to judge if the disk electrode breakdown voltage requirements are met for insulating liquids, as delivered from the manufacturer that have never been filtered or dried.
