What is the CT in a switch yard?
Current Transformers are used to measure alternating current (AC) in high-voltage circuits. They transform the high currents typically found in power lines into smaller, manageable currents that can be safely measured by instruments and meters. Current Transformers ensure that accurate readings are obtained without risking damage to the measuring devices or personnel.
These transformers operate based on the principle of electromagnetic induction, where the primary winding carries the high current to be measured, inducing a proportional current in the secondary winding. This secondary current is then used for measurement or control purposes.
Current Transformers play a vital role in protecting equipment and ensuring the efficient and safe operation of electrical systems by providing accurate current measurements for monitoring, control, and protective relay purposes.
