A Transformer Hipot Testing Report documents the results of high potential (hipot) testing conducted on a transformer to verify the insulation integrity of its windings. This test involves applying a high voltage—typically much higher than the operating voltage—between windings and ground to ensure no current leakage occurs. The report typically includes test parameters such as applied voltage, duration, leakage current readings, and test results (pass/fail). It may also outline environmental conditions and equipment used. This report is crucial for ensuring the transformer’s safety and reliability, especially before initial energization or after major repairs or rewinding procedures.
