A Transformer Hi-Pot (High Potential) Testing Report documents the results of high voltage insulation testing performed on a transformer to ensure its dielectric strength and insulation integrity. This test involves applying a significantly higher-than-normal voltage to the transformer's windings to detect any weaknesses, leakage currents, or insulation failures. The report typically includes test voltage levels, duration, leakage current readings, pass/fail status, and observations. Conducted during commissioning, maintenance, or after repairs, Hi-Pot testing is critical for identifying potential faults before energizing the transformer. A detailed report ensures safety compliance, operational reliability, and serves as a reference for future maintenance and audits.
