Reducing Transformer Oil Leakages in Projects

摘要

This paper discusses a study conducted on historical transformer oil leakages reported during projects at a major Oil Company. The objective was to identify means of reducing oil leak incidents and thereby reducing its impact to company projects and operations. The study involved review of all data reported over a 10-year period relating to transformer deficiencies during the electrical equipment manufacturing phase of many projects. All contributing factors to this problem were investigated and analyzed including the effectiveness of Source Inspection and testing requirements during the Manufacturing Stage of the transformers. The study revealed some identified risk inspection areas that need more attention during the manufacturing of transformers which may lead to oil leakages if not properly verified and successfully inspected. Examples of risk areas include the visual inspection of welds, and liquid penetrant testing prior to leak test.
