Test Method D should be used to determine the breakdown voltage of filtered and degassed liquids. Procedure B, modified in accordance with Section 17 of Test Methods Dis acceptable for testing silicone dielectric astm d877 if the requirements of 1.

For further information refer to RR: The voltage stress distribution between the parallel disk electrodes used in this test method are quasi-uniform and there is substantial stress concentration at the sharp edges astm d877 the flat disk faces. The use of Procedure B will result in a more accurate value of breakdown satm when testing such liquids. astm d877

Dielectric Breakdown Voltage

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Astm d877 Method D astm d877 not sensitive to low levels of these contaminants. Link to Active This link will always route to the current Active version of the standard.

Breakdown in this test method is dominated by events occurring at astm d877 electrode edges. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This test method should be used as recommended by professional organization standards such as IEEE C A low result in this astm d877 method indicates the presence of significant concentrations of one or more of these contaminants astm d877 the liquid tested. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

These liquids include petroleum oils, hydrocarbons, natural and synthetic astm d877, and askarels PCB used as insulating and cooling liquids in transformers, astm d877, and similar apparatus. Astm d877 values from the two systems may result in non-conformance with the standard. These liquids include petroleum oils, hydrocarbons, and askarels PCB used as insulating and cooling liquids in transformers, cables, and similar apparatus.

These may include samples taken from asgm breakers, load tap changers, and other liquids heavily contaminated with insoluble particulate material.
