What does CT stand for in electrical terminology?

In electrical terminology, CT stands for Current Transformer. Current transformers are essential devices used in power systems for measuring and monitoring current flow. They work by generating a secondary current proportional to the primary current, allowing for safe measurement and monitoring of high currents without directly connecting measuring instruments to high voltage systems.

The design helps ensure safety while providing accurate data for protection relays, meters, and other monitoring devices. They are widely used in substations and other high-voltage environments, making their understanding crucial for anyone in the field of electrical work or industrial electrician practices.
