Your authority in transformer testing

The Power Transformer Subcommittee of the IEEE has established standard transformer test procedures. These procedures are defined in the ANSI C57.12.90 for liquid-filled transformers and C57.12.91 for dry-type transformers. General requirements are documented in ANSI C57.12.00 and C57.12.01. Further detail is documented in the NEMA Standards Publication No. TR-1.

After testing your equipment, Sunbelt Solomon provides a detailed results report. These reports provide a baseline for the transformer and should be retained as a reference for future routine maintenance tests, such as TTR and Doble insulation tests. Sunbelt Solomon ensures that our measuring equipment is routinely calibrated to the NIST traceable calibration program.
