What is a PDF Current Transformer?
A current transformer (CT) is a type of instrument transformer used to measure alternating current (AC) flowing in a circuit. It works on the principle of electromagnetic induction, where the primary current flowing through the conductor induces a proportional secondary current in the CT winding. CTs are commonly used in power systems for measurement, protection and control purposes. They provide a reduced replication of the primary current, allowing safe and accurate measurement by instruments and relays.
How to define a transformer?
A current transformer (CT) is a vital component of electrical power systems used to accurately measure large currents. Its main function is to transform high primary currents into proportionally lower currents suitable for measurement by munitions, instruments or protective relays. The secondary winding of the CT is linked to measuring or protection devices, providing them with a reduced current proportional to the primary current. CTS ensures that these devices receive a safe and manageable level of current for precise monitoring and control of electrical systems.

The principle of current transformers (CTS) and potential transformers (PT) is based on electromagnetic induction. CTs operate by inducing a secondary current proportional to the primary current flowing through the conductor passing through the core of the CT. Similarly, PTs induce a secondary voltage proportional to the primary voltage across their terminals. CTS and PTS exceed high primary currents or voltages to lower, manageable levels suitable for measurement, control or protection purposes in electrical systems.
A transformer, in general, is a device that transfers electrical energy from one circuit to another by electromagnetic induction. In a transformer, this transfer occurs without any physical connection between the primary and secondary circuits. A transformer definition PDF would likely describe the fundamentals and working of transformers, including their construction, working mechanism, types and applications, often accompanied by diagrams and illustrations for clarity.
CT class refers to the accuracy class or rating of a current transformer (CT), which indicates the level of accuracy with which the CT can reproduce the primary current waveform under specified conditions. CTs are assigned different accuracy classes depending on their intended application and the accuracy required for the current measurement or protection. Common accuracy classes for CTS include class 0.1, class 0.2, class 0.5, class 1.0, and class 3.0, with class 0.1 being the most accurate and class 3.0 being the least accurate. Accuracy class is crucial to ensure reliable operation and performance of electrical systems, especially in measurement, monitoring and protection applications.
