Study Notes

The text discusses transformers, distinguishing between machines as either dynamic or static, with transformers falling under the static machine category.
Transformers are devices that transfer electrical energy from one circuit to another through electromagnetic induction.
Conductors are used in transformers to create an electric current, resulting in the generation of voltage difference when another conductor is brought close to it.
Transformers consist of a primary circuit (connected to the power source) and a secondary circuit (where the electrical measurements are taken), with isolation between them for safety and proper functioning.
The Instrument Transformer (IT) is a type of transformer used for measuring purposes and protection devices, providing the necessary current for fault protection actions.
Transformers ensure isolation between the primary and secondary circuits, allowing for accurate electrical measurements and safe operation of connected devices.
Different types of transformers include Current Transformers (CT) and Voltage Transformers (VT), each serving specific purposes in electrical systems.
Engineers must understand the relationship between voltage and current in transformers to ensure efficient and safe electrical operations.
