All voltage transformer manugacture form factory have to pass the routine test as follows
1. Verification of terminal markings.
2.Power-frequency voltage withstand test on secondary windings.
3. Power-frequency voltage withstand test on primary windings.
4.Partial discharge mensurement.
5.Determination of errors.
