Transformer testing and commissioning in a factory is a critical process that ensures safe, efficient, and reliable operation of power distribution systems. Before a transformer is put into service, it undergoes a series of rigorous tests to verify its performance, insulation strength, and compliance with international standards. The procedure typically includes insulation resistance test, winding resistance measurement, ratio test, polarity check, vector group verification, oil dielectric strength test, and partial discharge analysis. Factory commissioning further involves functional checks on protection relays, cooling systems, tap changers, and monitoring equipment. Engineers ensure that the transformer meets load requirements, maintains voltage stability, and performs under actual operating conditions. Proper testing and commissioning not only prevent costly failures but also extend the service life of transformers. This process guarantees safety, energy efficiency, and reliability in industrial, commercial, and utility power systems, making it a vital step before grid integration.
