The ACI Revenue Grade Solid and 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 Revenue Grade CTs come standard unterminated with ferrules for easy connection to any of the Single or 3 Phase power meters. The Revenue Grade CTs should only be used with the PowerscoutTM PS3037, PS12HD, PS48HD Power Meters in Revenue Grade or Tenant Billing applications. For best accuracy, the CTs should be selected based on the actual Window Size and the minimum and maximum operating currents for the circuits being monitored. Rocoil CTs should be used in applications in which the operating currents are in the 400A or greater range, since using more of the output scale will provide increased resolution than when monitoring lower current circuits. The CT-RGT12 Series solid core current transformers should be used in applications where exceptionally accurate signal transformation, low phase shift while exposed to harsh environmental operating conditions since it is epoxy encapsulated.
