What is the procedure for transformer oil testing report and what parameters are evaluated?

The procedure for a transformer oil testing report involves several key steps: sampling, laboratory analysis, and reporting. Initially, oil samples are collected following standard protocols to ensure representativeness. The parameters evaluated include dielectric strength, moisture content, acidity, dissolved gas analysis (DGA), and furan analysis. These tests assess the oil’s insulating properties, contamination levels, and overall condition, providing critical insights into the transformer’s health and performance.
