Standard Test Method for Gas Content of Cable and Capacitor Oils
 N D831/D831M

Annotation

This test method covers the determination of the gas content of electrical insulating oils of low and medium viscosities in the general range up to 190 mm2/s at 104°F [40°C], such as are used in capacitors and paper-insulated electric cables and cable systems of the oil-filled type. The determination of gas content is desirable for any insulating oil having these properties and intended for use in a degassed state.

NOTE 1-For testing insulating oils with viscosities of 19 mm2/s or below at 40°C, see Test Method D2945.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Метод стандартной пробы для содержания газа кабельных и конденсаторных масел

Этот метод тестирования покрывает определение газового содержания электрических изоляционных масел низких и средних вязкостей в общем диапазоне до 190 mm2/s в 104°F [40°C], те, которые используются в конденсаторах и изолированных бумагой электрических кабелях и кабельных системах масляного типа. Определение газового содержания желательно для любой изоляционной нефти, имеющей эти свойства и предназначенное для использования в дегазированном состоянии.
