An Outdoor Current Transformer (CT) is an instrument transformer designed for outdoor high-voltage installations. It reduces high line current to a safe standard value, usually 5A or 1A, for metering, protection, and monitoring.
Common applications include 11kV, 33kV, 66kV and higher-voltage substations, feeder panels, and transformer installations.
