A Rogowski coil is an electrical device used to measure alternating current (AC) with high accuracy, excellent linearity, and a wide dynamic range. It belongs to the family of non-intrusive current sensors and is commonly used in power monitoring, protection systems, and industrial automation. Unlike conventional current transformers (CTs), a Rogowski coil does not contain magnetic cores. Instead, it is made of a uniformly wound helical coil placed around the conductor being measured. The absence of a magnetic core gives it several advantages, including immunity to core saturation, lightweight structure, and excellent performance in measuring rapidly changing currents.
Although current transducers and current transformers (CTs) are both used to measure electrical current, they are not the same. They serve related but distinct purposes and operate on different principles. Understanding their differences is essential when selecting the right device for power monitoring, energy management, or industrial control systems.
You use current transformers to check how much electricity flows. These devices help you see how much energy you use. They make it simple to track your power use. Accurate readings from current transformers are important for homes and big buildings. You can put them on main feeds, subpanels, or sing
When you use a split core current transformer, your job gets easier and safer. This transformer opens up, so you can put it on without turning off the power. You save time and stay safe. You also spend less money because you do not have to take off wires or buy more tools. Many people pick split cor
