The Revenue Grade Split Core Current Transformers are designed to convert AC operating current into a low voltage AC signal for use with microprocessor based circuits that require maximum accuracy and precision. All Revenue Grade CTs come standard unterminated with ferrules for easy connection to any Single or 3 Phase power meters. The Revenue Grade CTs should only be used with the Powerscout™ PS3037, PS24, 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.
Applications
