CT
A Current Transformer (CT) is an instrument transformer that isolates and steps down high primary current to a much lower, standardized secondary current (e.g., 5A or 1A). It enables the safe and accurate measurement of current by meters and provides a proportional current signal to protective relays, control devices, and monitoring systems. Its core function is to allow large alternating currents to be safely monitored and controlled, making it indispensable for system protection, load analysis, and energy metering.
