The Crompton Greaves 5SFT-151 current transformer (CT) steps down high AC current to a proportional, lower secondary current for metering and protection equipment. The 5SFT-151 designation identifies the specific unit used in electrical systems to provide a safe, isolated signal from the primary conductor to sensing devices. Typical installations include distribution panels and control cabinets where accurate current measurement is required without exposing meters or relays to high-power lines.
