There are several advantages to using a transformer:
(1) Transformers allow for the expansion of the measurement range of meters and relays, making them more versatile in different applications.
(2) They provide significant benefits when it comes to extending the range of instruments and protective relays, enabling accurate measurements across a broader spectrum of conditions.
(3) One of the most important functions of a transformer is to isolate high voltage circuits from the measuring instruments, relays, and control circuits. This isolation ensures the safety of both the equipment and the personnel working with the system, reducing the risk of electrical hazards and damage.
In addition, transformers help maintain the accuracy of measurements by providing a proportional representation of the main circuit’s voltage or current. They also play a key role in power distribution systems, allowing for efficient transmission and utilization of electrical energy. By stepping up or stepping down voltages as needed, transformers contribute to the overall efficiency and reliability of electrical networks.
