Current Transformers and Shunts

Current transformers (CTs) and shunts are essential components used in electrical systems for measuring high currents indirectly with safety measures. Current transformers work by producing an alternating current (AC) in their secondary coil that is proportional to the current flowing through the primary coil, allowing for safe monitoring and control of electrical currents in power systems without any direct contact. They are commonly used in metering and protective relays in the electrical power industry. Shunts, on the other hand, are precision resistors used to measure direct current (DC) by creating a voltage drop proportional to the current, enabling accurate current measurement for both low and high currents.
