A Transformer Hi-Pot (High Potential) Testing Report documents the results of a high voltage insulation test conducted to assess the dielectric strength of transformer windings and insulation systems. This test applies a high voltage—usually much higher than the operating voltage—to verify the insulation's ability to withstand electrical stress without breaking down. The report includes details such as test voltage levels, duration, leakage current readings, and pass/fail results. It also lists the transformer's specifications, test conditions, and safety observations. A Hi-Pot Testing Report is essential for quality assurance, regulatory compliance, and verifying the transformer's readiness for commissioning or continued operation.
