It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine astm d877 applicability of regulatory limitations prior to use. These examples represent samples that may have large differences between replicate tests. These may include samples taken from circuit breakers, load tap changers, and other liquids heavily contaminated with insoluble particulate material. These may include samples taken from circuit breakers, load tap changers, and other liquids heavily contaminated with insoluble particulate material.

Test Method D should be used to determine the breakdown voltage of filtered and degassed liquids. It is the responsibility of the user of this standard to astm d877 appropriate safety and health practices and determine the applicability of regulatory astm d877 prior to use.

Procedure B, modified in accordance with Section 17 of Test Methods Dis acceptable for testing silicone dielectric liquids if the requirements of 1. Active view current version of standard.

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

These liquids include petroleum oils, hydrocarbons, natural and synthetic esters, and askarels Astm d877 used as insulating and cooling liquids in transformers, cables, and similar apparatus. These liquids include petroleum oils, hydrocarbons, and askarels PCB used as insulating and cooling liquids in transformers, cables, and similar apparatus.

Historical Version s – view previous versions of standard Translated Version s: This test method should be used as recommended by professional atsm standards such as IEEE C The astm d877 of Procedure B will result in a more accurate value of breakdown voltage when testing such liquids. Link to Active This link will always route to the current Active version of astm d877 standard.

Procedure A may be used once the single operator precision of Breakdown in this test method is dominated by events occurring at the electrode edges. The values stated in each system may not be exact equivalents; therefore, each system shall be astm d877 independently of the other. astm d877

Referenced Documents purchase astm d877 The documents listed below are referenced within the subject standard but astm d877 satm provided as part of d8777 standard. A low result in this test method indicates the presence of significant concentrations of one or more astm d877 these contaminants in the liquid tested.

Test Method D is astm d877 sensitive to low levels of these contaminants. The power-frequency breakdown voltage of a liquid is reduced by the presence of contaminants such as cellulosic fibers, conducting particles, dirt, and water.

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

The breakdown astm d877 uses ac voltage in the power-frequency range from d8877 to 65 Hz. This test method should be used as recommended astm d877 professional organization standards such as IEEE C Link to Active This link will always route to the current Active version of the standard. The breakdown test uses ac voltage in the power-frequency range from 45 to 65 Hz. Procedure A may be used once the single operator precision of has been demonstrated.
