Why is oil analysis conducted on transformers?

• A. To verify manufacturer compliance
• B. To assess the condition of transformer oil and detect issues
• C. To improve the thermal performance of the transformer
• D. To reduce maintenance costs

Answer: (B)

Conducting oil analysis on transformers is crucial for assessing the condition of transformer oil and detecting underlying issues that may not be visible through regular inspection methods. This analysis involves examining the electrical, chemical, and physical properties of the oil, which can provide insights into the performance and health of the transformer. Transformer oil serves multiple functions, including insulation and cooling. Over time, the oil can degrade due to various factors such as oxidation, moisture contamination, and the presence of conductive particles. By analyzing oil samples, technicians can identify the presence of harmful substances like dissolved gases, water content, and metallic contaminants, which indicate potential problems such as overheating or arcing within the transformer. Timely detection of these issues through oil analysis helps ensure that any problems are addressed before they lead to transformer failure, thereby enhancing the reliability and lifespan of the equipment. Thus, this proactive measure is essential for maintaining safe and efficient operation in substations.
