By stepping down the current level to a manageable value, CTs allow for precise monitoring and control of electrical systems. This is crucial for ensuring the efficient operation of equipment and preventing potential damage.
2. Overcurrent Protection: CTs provide a protective measure against excessive currents. In case of a fault or overload, CTs can quickly detect the sudden increase in current and trigger protective devices to isolate the faulty section. This helps in preventing equipment damage, fire hazards, and electrical accidents.
B. Working Principle of Current Transformers:
1. Primary and Secondary Windings: CTs consist of two windings: the primary winding and the secondary winding. The primary winding is connected in series with the electrical circuit carrying the high current, while the secondary winding is connected to the measuring or protection instruments.
2. Inductive Effect: When high currents flow through the primary winding, an alternating magnetic field is created. This magnetic field induces a proportional current in the secondary winding through electromagnetic induction. The current in the secondary winding is typically reduced to a standard value, making it suitable for measurement or control devices.
3. Turns Ratio: The turns ratio of a CT determines the transformation ratio between the primary and secondary winding. It is crucial to select the appropriate CT with the correct turns ratio to ensure accurate measurement and protection.
II. Voltage Transformers (VTs):
Voltage transformers, also known as VTs or potential transformers (PTs), are devices used for step-down voltage transformation. Similar to CTs, VTs are vital components of electrical systems, enabling accurate measurement and protection against overvoltage.
A. Importance of Voltage Transformers:

This is essential for maintaining system stability and ensuring equipment operates within safe voltage ranges.
2. Voltage Protection: VTs play a crucial role in protecting equipment from overvoltages. In situations where the incoming voltage exceeds the specified limits, VTs can swiftly detect the excess voltage and trigger protective measures to prevent potential damage to sensitive equipment.
B. Working Principle of Voltage Transformers:
1. Primary and Secondary Windings: Similar to CTs, VTs consist of primary and secondary windings. The primary winding is connected in parallel with the electrical circuit, while the secondary winding is connected to the measuring or protection devices.
2. Step-Down Voltage: When high voltages are applied to the primary winding, a corresponding low voltage is induced in the secondary winding. The turns ratio of the VT determines the magnitude of the step-down voltage.
3. Accuracy and Burden: The accuracy and burden of a VT are crucial factors to consider. Accuracy refers to the degree of agreement between the actual voltage and the indicated voltage, while burden represents the load imposed by the secondary instruments connected to the VT.
Current transformers and voltage transformers are indispensable components of electrical systems.
