# Voltformer Grid Standards Compatibility Checker

> A preliminary project-to-country electrical compatibility checker for frequency, nominal voltage and transformer vector group candidates. Unknown or incomplete inputs never produce a false pass. Utility confirmation, fault level, earthing, insulation coordination, protection and regulatory approval remain mandatory.

Use the checker at https://voltformer.com/grid-standards. Browse full country profiles at https://voltformer.com/country-profiles or call GET https://voltformer.com/api/v1/countries and POST https://voltformer.com/api/v1/countries/validate.

# Country grid compatibility checker

Screen transformer electrical parameters against preliminary country grid references.

## Inputs

Country, frequency (Hz), primary voltage (kV), secondary voltage (V), phases and vector group.

## Results

Compatible, incompatible or unknown checks with country-specific context.

## Interpretation and limits

A missing value is not a pass. Reference data does not establish utility acceptance, regulatory approval or site fault duty. Confirm final specifications with the local utility.
