The short circuit test for a transformer is a diagnostic procedure used to determine the transformer’s impedance, copper losses, and overall efficiency under loaded conditions. During this test, one side of the transformer (usually the low voltage side) is shorted, while the other side is supplied with a reduced voltage until rated current flows through the transformer. This method is critical in assessing the operational integrity of the transformer and is often employed alongside the open circuit test of transformer to provide a comprehensive evaluation of its performance. For precise measurements and detailed diagnostics, utilizing a high-quality industrial oil tester ensures accurate results and enhances the reliability of the test outcomes.
