Current Transformers

Current transformers make it possible to measure high current values and indicate these using instruments of a much lower rating. Owing to high costs in cable we recommend the use of a CT for the current measurement above 40A (unless otherwise specified).

When choosing a current transformer it is important to not only check the dimensions are suitable but also to check the accuracy class and burden required. You wll need to also consider the run of cable between the instrument and CT, size of the cable and the burden required which the instrument will consume. We have an extensive range and can accomadate most applications.
