What are Current Transformers (CT)? Current Transformers (CT) are electrical devices used to measure alternating current (AC) by producing a reduced current proportional to the current in its primary circuit. This allows for the safe and accurate monitoring of high current levels in various applications. CTs are designed to provide isolation and protection, making them essential in power systems and electrical panels. The primary uses of Current Transformers include energy management, metering, and protection in electrical systems. They are widely employed in substations, industrial plants, and commercial buildings to monitor electrical consumption, ensure safety, and facilitate the operation of protective relays. The relevance of CTs in the market is underscored by the increasing demand for energy efficiency and smart grid technologies, which require precise current measurements for effective management.
