AUTOMATIC TRANSFORMER COMPARATOR KATC-C1

The KATC-C1 Automatic Transformer Comparator is an enhanced version of the popular KATC-C Comparator.

This microprocessor-based comparator automatically selects the optimum measurement range, computes the results, and diplays the reference and test currents, the transformer ratio and phase angle errors, and the ANSI accuracy class for which the transformer qualifies. Measurement time is greatly reduced, as operator tasks are limited to connection of the transformer-under-test and adjustment of the test current. The capability to calculate and display the ANSI accuracy class eliminates the often difficult and time-consuming task of determining whether the measured results fall within the limits of the applicable ANSI parallelogram. The transformer ratio error can be displayed as Percent Error or Ration Correction Factor. Phase error can be displayed as Minutes or Milliradians.
