Study Notes
Transformer Function
- Transformers are essential components in electrical systems, primarily used to change the voltage of alternating current (AC) without altering its power.
AC Generation
- Alternators, also known as AC generators, are the key component responsible for generating alternating current (AC).
Transformer Applications
- Transformers are widely used in power transmission and distribution systems, where they play a vital role in reducing voltage losses during long-distance power transmission.
Transformer vs. Alternator
- Transformers modify existing AC voltage, while alternators generate AC voltage.
- This differentiation underscores their distinct functionalities within an electrical system.
Transformer Limitation
- Transformers often exhibit limited efficiency due to energy loss, primarily through heat dissipation during operation. This limitation can impact overall system performance.
