Current Transformers – Duncan Instruments Canada Ltd

Current Transformers

A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.

We offer a wide range of Current Transformers, 600V Class, for reducing high primary currents down to  5 Amp secondary current, for both measuring, relaying, and protection applications.

Square or donut CT’s with leads, or terminals are offered. Many current ratings and mounting options are available.

Omega 30 - series

The ANSI Metering Class transformers are intended for power monitoring applications where high accuracy and minimum  phase angle error are required. They are specially designed to be compliant with relevant ANSI standards.
