MS100

Current Transformer Test Set

Current Transformer Test Set MS100 is a computer-controlled equipment set that performs fully automatic calibration of current transformers with primary current from 0.5 to 5000 A

FEATURES AND BENEFITS

  • A complete set of equipment for Current Transformer testing
  • High accuracy (current error ± 0,005%; phase displacement ± 0,15 min)
  • Wide range of primary current: 0,5…5000 A
  • Rated secondary currents: 1 and 5 А
  • Rated power range:5 to 50 V·A at cosφ = 0,80; 0,5 to 50 V·A at cosφ = 1
  • FS measurement function
  • Cable, contact and internal test set (Comparator) resistances are compensated by four-conductor connection
  • Measurement process controlled by PC
  • Automatic test reports generation using basic or user-created templates
  • High productivity
