How Does A AKH-0.66 Series Measurement Current Transformer Work?

How Does A AKH-0.66 Series Measurement Current Transformer Work?

Measurement transformer is an instrument which converts the large current at the primary side into the small current at the secondary side according to the principle of electromagnetic induction. The current transformer consists of a closed core and windings. It has a small number of turns in the primary side winding and is strung in the line with the current to be measured. When the current transformer is working, its secondary loop is always closed, so the impedance of the series coils of the measuring instrument and the protection loop is very small, and the working state of the current transformer is close to short circuit.

AKH-0.66 Series Measurement Current Transformer FAQs

  • Use of current transformer?

    Current transformer is to convert high current value into low current value into meter, so as to measure whether the power system is accurate and safe.

  • What is a split core current transformer?

    Split core current transformer is designed for renovation projects without power outage and easy installation.

  • Why can't use a transformer with direct current?

    Because primary side current is too high can't directly access into meter.

  • How to choose the suitable current transformer?

    Accuronding to your input/output current,cable or busbar size can judge which ct sutiable.
