Y S Engineering Solution provides a crucial Transformer Oil Testing Service to diagnose the internal condition and extend the lifespan of power Transformers. This comprehensive service typically involves specialized on-site sample collection followed by laboratory analysis for several key parameters. Essential tests include Breakdown Voltage (BDV) testing to measure the oil's dielectric strength, which ensures proper insulation, and Moisture Content analysis to detect water, a significant contaminant that degrades insulation. Most critically, they perform Dissolved Gas Analysis (DGA), a non-intrusive test that identifies fault gases like hydrogen, acetylene, and methane, enabling the early detection of severe internal issues such as arcing or overheating before they lead to catastrophic failure. The results inform a data-driven approach to maintenance, often combined with Oil Filtration to restore oil quality.
