M100

Comparator


Comparator М100
is a precision test set for measurement of quantities used during the calibration and verification of Current and Voltage Transformers

FEATURES AND BENEFITS

  • Measurement of CT and VT errors, phase displacement, test current and voltage, resistance, conductance and power of burden
  • High measurement accuracy (CT and VT testing): up to ± 0,005 % and ± 0,05 min
  • VT testing requires the use of test and standard transformers with equal rated ratios
  • CT testing requires the use of test and standard transformers with equal rated ratios or 5:1 of secondary currents ratio
  • Possibility of using with automated CT and VT calibration system
  • Automatic test reports generation using basic or user-created templates

 


APPLICATIONS

M100 is used by:

  • Manufacturers of Current and Voltage transformers
  • On-site testing Current and Voltage  transformers
