The ACI Split-Core Current Transformers are designed to convert an AC operating current into a low voltage AC signal for use with microprocessor-based circuits that require maximum accuracy and precision.  ACI Split-Core CT’s come standard unterminated with ferrules for easy connection to any of the Single or 3 Phase Dent power meters.  Any of the split core CT’s can be used with any of the Powerscout^TM PS3037, PS12HD, PS48HD Power Meters in applications where typical power measurements are required and reduced accuracies are acceptable.  Where higher accuracies are required, refer to the Revenue Grade CT’s product data sheet for more detailed product information.  For best accuracy, the CT’s should be selected based upon the size of the conductors to be monitored by selecting the proper window size and using the expected maximum and minimum currents expected for the piece of equipment or branch circuit.  The acceptable Measurement Current Range is referenced in ordering grid table on the back of the product data sheet.  The CT-SCM and CT-SCL Series Current transformers are a cost-effective alternative to the Rocoil^TM CT’s but overall selection should be based upon the maximum and minimum currents being monitored.  All currents below the minimum measurement range will cause a “Snap to Zero” to occur which means that the power meter will show that no current is being consumed at that time thus affecting the reliability of your data.  Flexible Rocoil^TM CT’s provide a higher level of accuracy and should be used in applications with current levels of 600 Amps and larger.  The CT-HSC and CT-HMC Series current transformers with snap acting hinged design provide great performance, lower operating currents and easy installation in both new and retrofit installations.

Applications:   Energy and Demand Metering, Load Surveys, LEED/Green Projects, ROI / Project Justification
