Collection: Current Transformers

A current transformer (CT) is an electrical component that measures alternating current (AC) in a power system, by utilizing a step-down process where high alternating current flowing through a conductor is reduced to a safer level. Depending on the application, a metering device, protective relay, data logger, or SCADA system can be paired to measure the output current, which can be used to calculate the input current for monitoring, billing, or equipment protection purposes.
