Procedure B, astm d877 in accordance with Section 17 of Test Methods Dis acceptable for testing silicone dielectric liquids if satm requirements of 1. Procedure B, modified astm d877 accordance with Section 17 of Test Methods D, is acceptable for testing silicone dielectric liquids if the requirements of 1.

NTT – TECHNICAL BULLETIN: DIELECTRIC BREAKDOWN VOLTAGE

It is the responsibility astm d877 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These may include samples taken from circuit breakers, load tap changers, and other ashm heavily contaminated with insoluble particulate material. Active view current version of standard. Link to Active This link will always astm d877 to the current Active version of the standard.

The power-frequency breakdown voltage of a liquid is reduced by the astm d877 of contaminants such as cellulosic x877, conducting particles, dirt, and water.

It is the responsibility of the user of this astm d877 to astm d877 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These may include samples taken from circuit breakers, load tap changers, and other liquids heavily contaminated with insoluble particulate material.

The use of Procedure B will result in astm d877 more accurate value of breakdown voltage when testing such liquids. The breakdown test uses ac voltage in the astm d877 range from 45 to 65 Hz. Test Method D should astm d877 used to determine the breakdown voltage of filtered and degassed liquids. These liquids include petroleum oils, hydrocarbons, natural and synthetic esters, and askarels PCB used as insulating and cooling liquids in transformers, asttm, and similar apparatus.

For further information refer to RR: Link to Active This link will always route to the current Active version of the standard.

These liquids include petroleum oils, hydrocarbons, and askarels PCB astm d877 as insulating and cooling astm d877 in transformers, cables, and similar apparatus. Procedure A may be used once the single operator precision of has been demonstrated.

Dielectric Breakdown Voltage

Breakdown in this test axtm is dominated by events occurring at the electrode edges. Referenced Documents purchase separately The documents listed below are referenced within astm d877 subject astm d877 but are not provided as part of the standard.

This test method should be used as recommended by professional organization standards such as Astm d877 C The use of Procedure B will result in a more accurate astm d877 of breakdown voltage when testing such liquids. Historical Version s – view previous versions of standard Translated Version s: For astm d877 information refer to RR: This test method should be used as recommended by professional organization standards such as IEEE C Procedure A may be used once the single operator precision of Astm d877 Method D is not sensitive to low levels of these contaminants.

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

Historical Version s – view previous versions of standard. A low result in this test method indicates the presence of significant concentrations of one or more of these contaminants in the liquid tested. Combining values from the two systems astm d877 result in non-conformance with the standard. The voltage stress distribution between the parallel disk electrodes used in this test method are quasi-uniform and there is substantial adtm concentration at the sharp edges of the flat disk faces.

These examples astm d877 samples that may have large differences between replicate tests. The breakdown test uses ac voltage in the power-frequency range from 45 to 65 Hz. These examples represent samples that may have large differences between astm d877 tests.
