Current Transformers
Intellimeter offers a wide variety of Current Transformers, Split-Core, and Solid-Core for the most common circuit sizes.
The current transformers supply the meter with a current proportional to that of the main circuit of sufficiently reduced amplitude for an accurate measurement.
The measuring devices cannot be directly connected to the high-magnitude supplies. Hence current transformers are used to supply those devices with currents of magnitude proportional to those of power.
- The 100 mili-Ampere secondary types of current transformers, are small in size and intrinsically safe, or self shorting eliminating the need for shorting blocks or a separate current transformer cabinet
- Transformers with a 5 Ampere. secondary require shorting blocks, also available through Intellimeter
- All the solid core current transformers are Revenue Grade and Approved by Measurement Canada
- Our latest models are UL approved
