DGA (Dissolved Gas Analysis) standards are reference materials used for calibrating instruments and ensuring the accuracy of measurements related to the analysis of dissolved gases in insulating oil. These standards typically consist of gas mixtures with known concentrations of gases commonly found in transformer oil, such as hydrogen (H2), methane (CH4), ethylene (C2H4), ethane (C2H6), acetylene (C2H2), carbon monoxide (CO), carbon dioxide (CO2), and oxygen (O2), among others.
DGA standards are essential for industries involved in the monitoring and maintenance of electrical transformers, where the analysis of dissolved gases can provide valuable insights into the condition and health of the transformer. By calibrating instruments with DGA standards, operators can accurately detect and quantify the concentration of gases dissolved in transformer oil, helping to identify potential faults, overheating, or degradation of insulation materials.
