A Comprehensive Transformer Service involves a range of activities designed to maintain the optimal performance, safety, and longevity of the equipment. This includes both preventive and corrective actions. Preventive services typically involve routine inspections, cleaning, and oil testing to assess the transformer's health and detect potential issues before they cause a failure. Key tests include Dissolved Gas Analysis (DGA) and dielectric strength tests of the oil. Corrective services address specific problems, such as repairing winding failures, replacing bushings, or fixing oil leaks. These services are essential for industrial and utility clients to ensure a reliable power supply, minimize costly downtime, and comply with safety regulations.
