Questions with Current Sense Transformers

  • Ask: What does a current transformer do?

    Answer: A current sense transformer (CT) operates in exactly the same way as any magnetic transformer and follows the basic rules that voltage and current are transformed in the ratio of the primary and secondary winding turns, load impedance is transformed in the ratio of the square of the turns and the volt-second product ...

  • Ask: What is CT and PT in transformer?

    Answer: 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.

  • Ask: How do you connect a current transformer?

    Answer: CT and PT stand for Current Transformer and Potential Transformer. Both are instrumentation transformers. CT measures current PT measures voltage. CTs are used in clamp meters. and in industries, CTs measure High Currents and PTs measure high voltages.

  • Ask: What is current transformer burden?

    Answer: Current transformer burden is defined as the load connected across its secondary. It is generally expressed in VA(volt-ampere). As the rated secondary current in case of CT is 5 ampere so its burden can also be expressed in terms of impedance at rated secondary current at given power factor(generally 0.75 lagging).
