Winding testing of a transformer involves evaluating the condition and integrity of its windings through various electrical tests. Common winding tests include resistance measurement, insulation resistance, and inductance checks. Resistance testing helps identify issues like loose connections, broken strands, or imbalanced phases by comparing readings across all windings. Insulation resistance tests assess the quality of insulation between windings and ground. These tests are essential during manufacturing, commissioning, and routine maintenance to ensure reliability and performance. Abnormal readings can indicate problems such as shorted turns, overheating, or moisture ingress. Regular winding tests help prevent failures and extend the transformer’s operational life.
