Jan 20, 2018The % of primary voltage that is required to produce the rated secondary current is what is known as %impedance or per-unit impedance. There is another way of defining the %Z or % Impedance or leakage reactance. A transformer is a nothing but two (or more) coils coupled by magnetic field.

  • Current transformer - Wikipedia

    A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.Instrument transformers scale the large values of voltage or current to small,
