1. Current Transformer (CT) A Current Transformer is an instrument transformer used to measure alternating current (AC) by stepping down high currents to a lower, measurable value. Key Functions: Current Measurement: Steps down high primary current (e.g., 1000A) to a standardized secondary current (e.g., 5A or 1A) for meters and relays. Isolation: Provides galvanic isolation be...
