Transformation Ratio | current transformer,potential transformer

This page mentions Transformation Ratio definition. It mentions Transformation Ratio formula or equation for current transformer and potential transformer.

Transformation Ratio

Definition:
Transformation Ratio is the ratio of magnitude of the primary phasor to the secondary phasor. This term is used in instrument transformer.
➤ R = |Primary Phasor| / |Secondary Phasor|

Transformation Ratio for current transformer

It is the ratio of primary winding current and secondary winding current.
➤ R = primary winding current/secondary winding current

Transformation Ratio for potential transformer

It is the ratio of primary winding voltage and secondary winding voltage.
➤ R = primary winding voltage/secondary winding voltage
