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.
