Introduction to basic knowledge about current transformers

Introduction to basic knowledge about current transformers A current transformer produces an alternating current in the secondary that is proportional to the current in the primary. By having a known turns ratio, the currents in the primary and secondary are connect, and if the current in the secondary is measure, the current flowing in the… Continue reading Introduction to basic knowledge about current transformers

What does a transformer do?

What does a transformer do? Transformers: divided into voltage transformer, current transformer, zero sequence transformer, etc. Voltage transformers: converts different voltages into a unified value to match the instrument or meter. The secondary voltage is mostly 100V or 220V. Current transformers: Change different currents into a unified current value to match the instrument or meter.… Continue reading What does a transformer do?
