A Transformer Oil Testing Service is a critical maintenance procedure used to assess the health and condition of a transformer's insulating fluid. The oil serves two primary functions: to provide electrical insulation and to dissipate heat generated by the transformer's core and windings. The testing service involves a series of laboratory analyses, including dielectric strength tests to measure the oil's insulating capability, moisture content analysis to check for water ingress, and dissolved gas analysis (DGA) to detect internal faults. Regular testing helps to identify potential issues early, preventing costly equipment failure, extending the transformer's lifespan, and ensuring safe and reliable operation. This service is essential for asset management in industries that rely on high-voltage equipment.
