ICT127
Isolated Current Transformer

Image of ZERA ICT127 Isolated Current Transformer
Nominal current 100 A (max. 120 %)
Primary current 0.002 A ... 120 A
Secondary current 0.002 A ... 120 A
Main functions
  • Galvanic isolation of current and voltage for testing of meters with closed link
  • Combined, electronic error compensation
  • Communication via WinSAM
Scope of application
  • Testing of single- or three-phase meters with closed link
  • Burden measurement (optional)
  • Breaker test (optional)
  • For testing three-phase meters there is one ICT required for each test position.
  • For testing single-phase meters, one ICT can be used for testing max. three meters.
Specials
  • Ratio 1 : 1 @ 12 A ... 120 A
  • Ratio 10 : 1 < 12 A
  • Especially suitable for testing CT operated meters of the latest generation
  • Very high accuracy for current < 12 A
