POLYLUX’S TI SERIES

The TIB, TIP and TIN series are current transformers designed to be used as instrument transformers for energy monitoring or as protection transformers to generate current for protection relays.

We can subdivide the TI current transformer series into three series:

  • TIB series Primary winding · Primary current 10-25 A · Secondary current 5 A
  • TIP series Through primary · Primary current 40-500 A · Secondary current 5 A
  • TIN Open core series (SPLIT) Primary current 400-1500 A Secondary current 5 A
