Current Transformers

The latest current transformers from Crompton Instruments and Smart Process & Controls 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 Current Transformer 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 will need to also consider the length of cable between the instrument and CT; size of the cable and the burden required which the instrument will consume. In retro-fit applications it is possible to use a Split Core Current Transformer as it is easier and faster to install. These also come in various sizes and current ratings. We have also developed the Three Phase Current Transformers with plug in connectors for fast installation. Our Single Phase Solid Core Current Transformers come in various different shapes and sizes to cater for most busbar or cable dimensions.
