General Electric 460-480 Instrument Transformer steps down high line voltage to a safe level for metering and protection circuits. It has a primary rating of 460–480 V and a turns ratio of 4:1, yielding a secondary voltage of approximately 115–120 V depending on the exact primary voltage. This unit is designed for use in electrical distribution environments where accurate voltage measurement is required by meters, relays, or control equipment. Typical applications include metering and protective relaying in industrial or commercial power systems using 460–480 V service.
