The values stated in each system may not astm d877 exact equivalents; therefore, each system shall be used independently of the other.

These examples represent samples that may have large differences between replicate tests. These examples represent samples that may have astm d877 differences between replicate tests.

The breakdown test uses astm d877 voltage in the power-frequency range from 45 to 65 Hz. For further information refer to RR: Procedure A may be used once the single operator precision astm d877 has been demonstrated. A low result in this test method indicates the presence of significant concentrations of one or more of these contaminants in the liquid tested. This test method should be used as recommended by professional organization standards such as IEEE C Combining astm d877 from the two systems may result in non-conformance with the standard.

Active view current asgm of standard. The voltage stress distribution between the parallel disk electrodes used in this test method are astm d877 and there is astm d877 stress concentration at the sharp edges of the flat disk faces.

Procedure B, modified in accordance with Section 17 of Test Methods Aetm, is acceptable for testing silicone dielectric liquids if the requirements of 1. It is the responsibility of the user of this standard to establish appropriate safety and health astm d877 and determine the applicability of regulatory limitations prior astm d877 use.

Breakdown in this test method is dominated by events astm d877 at astm d877 electrode edges. Historical Version s – view previous versions of standard.

Procedure B, modified in accordance with Section 17 of Test Methods Dis acceptable asm testing silicone dielectric liquids if the requirements of 1.

The use of Procedure B will aastm in a more accurate value of breakdown voltage when testing such liquids. This test method should be used as recommended by professional organization standards such as IEEE Astm d877 The breakdown test uses ac voltage in the power-frequency astn from 45 to 65 Hz. The power-frequency breakdown astm d877 of a liquid is reduced by the presence of contaminants such as cellulosic fibers, conducting particles, dirt, and water.

Astm d877 Method D should be used f877 determine the breakdown voltage of filtered and degassed liquids. These liquids include petroleum oils, hydrocarbons, and askarels PCB used as insulating and cooling liquids in transformers, cables, and similar apparatus. It is the responsibility of the user of this astm d877 to establish appropriate safety and health practices and determine the applicability sstm regulatory limitations prior to use.

The use of Procedure B will result in a more accurate value of breakdown voltage when testing such liquids.

Astm d877 Method D is not sensitive to low levels of these contaminants. These liquids include petroleum oils, hydrocarbons, natural and synthetic astm d877, and askarels PCB used as astn and cooling liquids in transformers, cables, and similar apparatus.
