Due to the dynamic nature of the power sector, transformer oil analysis in India has become a crucial component of electrical infrastructure maintenance. Extending beyond the scope of a routine inspection, this diagnostic technique serves as a tool for diagnosing and predicting the transformer operation, ensuring a reliable and continuous supply of electricity across diverse regions.

Imperative need for transformer oil analysis

The need for transformer oil analysis in India cannot be overstated. This procedure is required for detecting potential issues within transformers, which serve as an integral component of the national power grid. Analyzing the oil, engineers can understand the actual state of a transformer and predict its performance. This foresight is crucial to averting the failures, minimizing the downtime, and ensuring the longevity of these power assets. Through this analysis, technicians can detect signs of wear, contamination, and degradation, which are key to scheduling the timely maintenance and preventive actions.

Parameters for basic transformer oil analysis

Conducting a basic transformer oil analysis involves evaluating the following array of parameters:

• Dielectric Strength: the test evaluates the ability of oil to withstand electrical stress. Lower dielectric strength indicates a higher likelihood of electrical failures within the power equipment.
• Moisture Content: water is a critical threat to transformer oil, as it degrades its insulating properties. Accurate measurement of moisture content is essential for maintaining the integrity of oil and, consequently, the overall integrity of transformer.
• Tangent Delta Test: the test measures the dissipation factor (or loss angle) of transformer oil, which is critical for evaluation of its insulating quality. A decrease in tangent delta values indicates the insulation degradation, which potentially reduces the transformer efficiency and poses a component failure risk. 
• Interfacial Tension (IFT): the test helps in detecting the presence of polar compounds and contaminants. A decrease in IFT values may indicate the presence of oxidation products, which signals the onset of oil aging or contamination.

Each of these tests provides essential data points that offer a comprehensive overview of transformer state when combined. These data are useful in making informed decisions on maintenance strategies for efficient operation of the power grid in India.

Parameters for comprehensive transformer oil analysis

In addition to basic tests, a comprehensive transformer oil analysis allows professionals to delve deeper, incorporating a broader range of parameters that provide a more detailed understanding of the transformer state:

Dissolved Gas Analysis (DGA): this advanced test helps in detecting the gases, such as hydrogen, methane, and ethylene, dissolved in insulating oil. These gases may indicate various types of transformer issues, such as overtemperature, arcing, or insulation degradation. DGA is crucial to preventive maintenance, allowing for early detection of faults that might not be evident during other tests.

Furan Analysis: this parameter evaluates the concentration of furan compounds in oil; furans are byproducts of the windings insulation degradation. High levels of furans suggest significant aging of insulation, providing insight into the internal state of transformer, which is otherwise not visible.

Particle Count: the test measures the size and number of particulate contaminants in oil. This test evaluates the purity of oil and identifies the potential wear and tear of transformer components.

PCB Content: a test for polychlorinated biphenyls (PCBs) is a must, given their toxic nature and the environmental hazards they pose. The PCB test ensures compliance with environmental safety standards and evaluates contamination levels in older transformers that might still contain PCBs.

These comprehensive tests offer a more comprehensive insight into the transformer state, allowing for more precise and targeted maintenance interventions. This in-depth analysis is key to extending the lifespan of transformers and ensuring their optimal performance in the challenging power distribution environments of India.
