Transformer Test Report Generator

Enter routine test results from your test bay and generate a formatted, standards-referenced PDF report — ratio, resistance, no-load loss, load loss & impedance, insulation resistance and dielectric tests, per IEC 60076-1 §11. This tool formats the report from values you enter; it does not connect to test equipment.

Remarks

This tool formats a report from the values you enter — it does not verify measurement accuracy or connect to test equipment. Compare all results against the applicable IEC 60076-1 / IEEE C57.12.90 tolerance tables before issuing to a customer.
