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

The procedure for transformer oil test equipment involves sampling the oil, followed by various tests to evaluate its properties. Key parameters evaluated include dielectric strength, moisture content, acidity, dissolved gas analysis (DGA), and furan analysis. These tests help assess the oil’s insulation performance, contamination levels, and overall health of the transformer. Proper calibration and adherence to ASTM or IEC standards are essential for accurate results.
