Nominal Ratio | current transformer,potential transformer
This page mentions Nominal Ratio definition. It mentions Nominal Ratio formula or equation for current transformer and potential transformer.
Nominal Ratio is the ratio of rated primary winding current (or voltage) to the rated secondary winding current (or voltage).
This term is used in instrument transformer.
Nominal Ratio for current transformer
It is the ratio of rated primary winding current and rated secondary winding current.
➤ Kn = rated primary winding I/rated secondary winding I
Nominal Ratio for potential transformer
It is the ratio of rated primary winding voltage and rated secondary winding voltage.
➤ Kn = rated primary winding V/rated secondary winding V
