Current transformers (CTs) are compact devices used in electrical power systems to accurately measure and transform high currents for monitoring and protection. They employ electromagnetic induction to replicate current from a primary circuit to a secondary circuit with reduced levels. CTs are widely utilized in power generation, substations, and industrial settings, working alongside instruments such as ammeters and protective relays. They play a critical role in fault detection, ensuring the safety and efficiency of power networks. CTs’ adaptability to various current ratings and their ability to handle high currents make them indispensable components for accurate current measurement and control in modern electrical systems.
