Summary This standard specifies the vacuum insulating oil pressure method gas content measurement methods. This standard applies to oil-filled electrical equipment insulating oil and gas content measurement for kinematic viscosity (40��C) is not greater than 4Omm2/s of other oil -containing gas may be determined with reference to the standards. This standard is divided into A method (electronic vacuum gauge method) and Method B (U -shaped differential manometer oil column method).
