Which chemicals are known to interact with transformer oil?

Transformer oil is primarily composed of mineral oil and is used for insulation and cooling in transformers. Certain chemicals can interact with transformer oil, leading to degradation or changes in its properties.

When considering the chemicals identified in the question, both A and B exhibit characteristics that can cause interactions with the transformer oil. For instance, certain additives or impurities may react or dissolve in the oil, potentially affecting its performance and safety.

Thus, identifying both A and B as chemicals that can interact with transformer oil illustrates the importance of monitoring the quality and chemical composition of the oil to ensure the reliable operation of electrical equipment. Understanding these interactions helps in maintenance and operational decisions that can prolong the life and efficiency of transformers.
