ActiveDetermination of acid number in transformer oils and turbine oils by BTB method
变压器油、汽轮机油酸值测定法（BTB法）
Application Summary AI generated
This standard specifies the BTB (bromothymol blue) method for determining the acid number in transformer oils and turbine oils. It is applied in the electrical power industry and industrial lubrication systems to assess oil degradation and acidity levels, ensuring the safe operation of transformers and turbines. The method is used during routine maintenance and quality control testing to monitor oil condition and predict remaining service life.
