Project TA04020151 – Enhancement of the power transformer operation security and prevention of their failures caused by the corrosive sulphur effect

The primary objective of the project is to develop, emipiricaly verify, and implement a comprehensive methodology to improve the safety of power transformer operations and prevent failures caused by corrosive sulphur.

As part of the project, the following key objectives are addressed:

• A comprehensive review and assessment of existing knowledge regarding the presence of corrosive sulphur in transformer insulating oils and the associated risks to their safe operation.
• Development and practical validation of diagnostic and analytical methods for identifying and quantifying specific compounds present in transformer insulating oils.
• Identification of individual compounds responsible for the presence of corrosive sulphur in insulating oils, along with a description of the reaction mechanisms involved in their formation or transformation.
• Development of methodical guidelines for assessing different types of insulating oils used in operating transformers, focusing on the amount and characteristics of the corrosive sulphur present and the associated risks to the safe operation of transformers.
• Proposed methods to eliminate corrosive sulphur from transformer insulating fluids and other energy equipment.‍
• Development of a comprehensive methodology that fully describes the phenomenon of corrosive sulphur in insulating fluids of transformers and other energy equipment, including proposing methods to enhance the operational safety of power transformers and prevent failures caused by corrosive sulphur.
• Validation of project results in real-world energy equipment operations.
