Current transformers are vital for accurate current measurement and safety in electrical systems. These devices are specifically designed to reduce high currents to lower, more manageable levels, which can be safely analyzed by monitoring equipment. CT transformers are essential in various applications, from power generation to distribution and industrial processes. They play a crucial role in system protection by providing critical data for fault detection and operational control. Available in several designs to meet diverse requirements, CT transformers enhance the precision and reliability of electrical infrastructure management.
