Testing procedures include routine tests like insulation resistance measurement, turns ratio verification, winding resistance measurement, and dielectric tests to assess insulation strength. Specialized tests such as impulse tests simulate lightning strikes to check surge protection. Thermal tests evaluate cooling performance under load. Partial discharge tests detect insulation defects. Tests are conducted according to industry standards (e.g., IEC, IEEE) and can be performed in manufacturing facilities, during commissioning, or as part of maintenance programs to ensure transformers meet performance and safety requirements.
