Current transformers (CTs) are widely used in power systems. Current transformers, along with voltage or potential transformers, are instrument transformers, which. Current Transformers produce an output in proportion to the current flowing through the primary winding as a result of a constant potential on the primary The Current Transformer ( C. They sense the current on the high-current cable and convert it into a corresponding small current signal for instrument measurement and relay protection. CTs lower high voltages to safer levels. This makes it easier for meters and protective relays to read the current. The invention of a practical, efficient transformer.
Current transformers step down the monitored current to a secondary (output) range of 0 to 5 amps AC to power the protective relay. That operates on the principle of Kirchhoff's Current Law (KCL), which states that the. As you should already know, current transformers are used for metering and relay protection purposes. Metering transformers may have very significant errors during. Protective relays measure specific process variables such as current or voltage and, based on their value, switch the output. Thus, the main function of the protective relay is to trip the breaker under abnormal operating conditions.
