Current Transformers
Current Transformers (CTs)
Current Transformers (CTs) are essential components for accurately measuring alternating current (AC) in electrical systems. They function by producing a secondary current proportional to the primary current, enabling safe and precise monitoring and control.
At Duncan Instruments, we offer a comprehensive selection of 600V Class CTs, designed to reduce high primary currents down to a standard 5 Amp secondary current. Our inventory includes various models suitable for measuring, relaying, and protection applications.
Product Highlights:
- Design Options: Choose from square or donut-shaped CTs, available with leads or terminals to suit different installation requirements.
- Current Ratings: A wide range of current ratings to match your specific application needs.
- Mounting Flexibility: Multiple mounting options to accommodate various setups.
- Compliance: Our ANSI Metering Class transformers are engineered for power monitoring applications requiring high accuracy and minimal phase angle error, ensuring compliance with relevant ANSI standards.
Available Models:
We’ve simplified our CT catalog into 8 core styles—each available in multiple sizes and ratios.
