Transformer Oil Course – All Levels
Transformer Oil Course covers basic, intermediate and master’s level. You can subscribe individually, or to all levels at once.
All levels topics are listed here:
BASIC LEVEL
1. An introduction to transformer oils – A brief review of transformer types based on insulation systems
2. Essential properties of oil in relation to performance
3. Oil standards – Basic concepts and key differences
INTERMEDIATE LEVEL
1. Mineral oils in service – Storage, handling, filling into transformers, limits for parameters before energizing, testing oils for compatibility, sampling of oil
2. Condition monitoring of oils in service, their limits and recommended actions, interaction among oil parameters, sampling precaution for water
3. Reconditioning and reclaiming of mineral oils – Criteria for making decisions, and methods employed
4. Gassing tendency, stray gassing and DGA – Definitions, test methods and their importance for a transformer in operation
5. Additives in oil – Their chemistry, conferred benefits and pitfalls
6. Alternative fluids – R-temp, silicones, esters, GTL fluids – their origin and comparison with mineral oils and among themselves
MASTER’S LEVEL
1. Moisture dynamics – Changing equilibrium in a transformer and its interpretation on the asset health
2. Oxidation of oil – Mechanisms in a transformer, consequences of ageing of oil and corrective actions
3. Copper corrosion – Major causes, mechanisms and mitigation techniques
4. Furanic compounds – Mechanism of formation in a transformer, analysis, interpretation on paper degradation
5. Emergence of methanol as a chemical marker for paper degradation
6. DGA of mineral oils – Chemistry of formation of different gases and principles of interpretation methods
7. HSE aspects in mineral oils – A comparison with alternative fluids
8. Dielectric properties – A comparison of mineral oils and ester fluids
9. An objective assessment of alternative fluids vis-à-vis mineral oils – Performance, stability, design, cost
