What is the corrosive sulfur test in transformer oil?

The corrosive sulfur test in transformer oil is a crucial diagnostic procedure designed to assess the presence of corrosive sulfur compounds that can lead to significant damage in transformer components. This test identifies the oil’s ability to cause galvanic corrosion in copper materials typically used in transformers. Using specific methodologies and equipment like the Globecore products, the testing indicates whether the transformer oil is safe for use or if it contains harmful levels of corrosive sulfur that could compromise the integrity of the transformer. It is essential for maintaining the longevity and reliability of transformer systems.
