What is the procedure for ift test of transformer oil and what parameters are evaluated?

The procedure for the Insulation Fluid Test (IFT) of transformer oil involves sampling the oil, followed by laboratory analysis. Key parameters evaluated include dielectric strength, moisture content, acidity, and dissolved gas analysis (DGA). The dielectric strength assesses the oil’s insulating properties, while moisture content indicates potential degradation. Acidity measures the oil’s condition, and DGA identifies any internal faults. Regular IFT ensures the transformer operates efficiently and safely.
