IME BTA2 TAEB Primary Winding Summation Current Transformer (From 2 to 6 Equal Primary Inputs)


  • Summation current transformer (formerly BTA2)
  • Summates from 2 to 6 equal inputs (1A or 5A Secondary)
  • Accuracy : class 0.5
  • Unequal inputs on request


A range of current transformers to summate currents from various current transformer secondary sources and provide a proportional current output. The TAEB may be used to summate CT inputs of the same, or different, ratios. When summating three phase circuits, it is necessary to summate like phases ie L1-L1, L2-L2, L3-L3.

From 2 to 6 single-phase input current summation transformer. It effects the vectorial sum of the currents of many lines in just one voltage system. It is essential when the main C.T. ratios are not the same.
