  • Insulating Oil for Circuit Breaker Insulating Oil for Circuit BreakerGeneralThe requirements of insulating oil used in circuit breakers, as distinguished from insulating oil used in transformers, are uniquely different. Modern oil circuit breakers require low viscosity and low pour-point oil because a large percentage of them are used ...
  • Suggested limits for continued use of service-aged insulating oil Suggested limits for continued use of service-aged insulating oila. Alternative measurements of 1.0 mm (0.04 in) and 2.0 mm (0.08 in), respectively, for gaps.b. The ppm moisture values shown are based on consensus, which are also given in IEEE Std 637. These values should not be used to infer solid insulation ...
  • Chemical Test for Mineral Insulating Oil Chemical Test for Mineral Insulating OilGas content - ASTM D2945, ASTM D3284, and ASTM D3612The gas content of an insulating fluid may be defined as the volume of dissolved gas per 100 volumes of oil, at standard pressure and temperature. Some types of equipment require the use of electrical insulating ...
  • Electrical Test for Mineral Insulating Oil Electrical Test for Mineral Insulating OilDielectric breakdown voltage - ASTM D877 and ASTM D1816The dielectric breakdown voltage of insulating oil is a measure of its ability to withstand voltage stress without failure. It is the voltage at which breakdown occurs between two electrodes under prescribed ...
  • Physical Test for Mineral Insulating Oil Physical Test for Mineral Insulating OilAniline point - ASTM D611The aniline point (temperature) of a mineral insulating oil indicates the solvency of the oil for some materials that are in contact with the oil. A high aniline point indicates a lower degree of aromaticity and a lower solvency for some ...
