Winding testing of transformers is a key diagnostic process used to assess the health and integrity of transformer windings. It includes several tests such as winding resistance, insulation resistance, and polarity checks to detect issues like shorted turns, loose connections, or deterioration in insulation. These tests help ensure that the windings are properly installed, balanced, and capable of handling operational loads safely. Winding testing is typically performed during manufacturing, commissioning, or preventive maintenance. Accurate test results help identify early signs of failure, improve reliability, and extend the transformer's service life. This testing is vital for safe and efficient transformer performance.
