In modern industrial facilities, energy management and system safety are just as important as production itself. At this point, current transformers (CTs), which are used to accurately measure and analyze electric current, have become one of the fundamental building blocks of electrical systems. So, what exactly is a current transformer and why is it so important?
What is a Current Transformer?
A current transformer is a measuring device that converts high currents into smaller, measurable values. It is generally used together with meters, protection relays, and energy monitoring systems. Since directly measuring high-voltage lines would be risky and costly, the current transformer reduces the current to standard values such as 1A or 5A.
