What is a current transformer?

Current transformers (tc), also known as intensity transformers (ti), also known as current measuring transformers, play an essential role in electricity management. They convert high currents into lower ones, making it easier to measure and protect electrical equipment. Current transformers consist of a core, a primary winding and a secondary winding. When an alternating current flows through the primary winding, it generates a magnetic field which induces a proportional alternating current in the secondary winding. This reduces the current to a safe level for measurement and monitoring with an ammeter.


What does a current transformer do?

The main role of a current transformer is to measure and reduce the high alternating current present in an electrical circuit, to make it compatible with equipment measurement or protection requirements. They are widely used in a variety of fields, including generator stations, electrical substations, commercial power distribution, power measurement equipment, overcurrent protection devices and power network analyzers.


What types of current transformers are there?

There are three main types of current transformer:
  • Step-down transformer: this type of transformer is used to reduce the secondary voltage relative to the primary voltage. It is commonly used to adapt the voltage of electric current to the specific needs of devices or systems, by converting a high voltage into a lower one.
  • Isolation transformer: unlike conventional transformers, the isolation transformer has primary and secondary windings with an equal number of turns and a transformation ratio of 1:1 (or very close to 1:1). This means that the input voltage is equal to the output voltage, making it possible to electrically isolate circuits while maintaining the same voltage.
  • Step-up transformer: step-up transformers convert a low primary voltage into a higher secondary voltage. They are used, for example, in inverters and stabilizers to raise the voltage when electronic components or elements require a higher voltage.
In short, current transformers play a crucial role in electricity management by transforming high currents into lower ones, enabling accurate measurement and effective protection of electrical equipment.
