Transformer impedance pdf . Due to the trend toward lower impedance transformers for better voltage regulation the actual transformer impedances may deviate from the nema standard given at left. Impedance agree with its nameplate its major insulation structure is intact wiring insulation has not been bridged and the transformer is ready for service.
