Project TA04020151 — Improving the safety of operation of power transformers and prevention of accidents due to corrosive sulphur

The main objective of the project is the development, practical verification and implementation of a comprehensive methodology for increasing the safety of operation of power transformers and prevention of accidents due to the action of corrosive sulfur.

The following sub-objectives are addressed in the project:

• Summary and evaluation of existing information on the presence of corrosive sulphur in transformer insulation oils and risks to their safe operation.
• Development and practical verification of diagnostic and analytical methods for identification and quantification of individual types of compounds present in insulating transformer oils.
• Identification of individual compounds responsible for the phenomenon of corrosive sulphur in insulating oils and description of reaction mechanisms of their formation or changes.
• Methodological proposal for evaluation of individual types of insulating oils actually used in operating transformers in terms of quantity and character of corrosive sulphur present and the resulting risks to the safety of transformer operation.
• Design of ways to eliminate corrosive sulfur present in insulating fluids of transformers and other power equipment.
• Elaboration of a comprehensive methodology describing the phenomenon of corrosive sulfur in insulating fluids of transformers and other power equipment, including proposals for increasing the safety of operation of power transformers and prevention of accidents due to the action of corrosive sulfur.
• Verification of project results in practical operation of power plants.
