CT-1S Summation and Multiplier Toroidal Current Transformer

The main advantages of CT-1S Summation and Multiplier Toroidal Current Transformer are listed below:

  • Eliminates cable section limits.
  • Solutions up to 250 A earth leakage. 

If one of the toroidal transformer is not big enough and all power lines cannot fit in to one toroidal current transformers, CT-1S Summation and Multiplier Toroidal Current Transformer can be used easily as the solution. Toroidal earth leakage transformers can be used on the each of power line (each phase and neutral cable) and collected with CT-1S for vectoral summation. 

The toroidal Current Transformer which used with CT-1S must be same type and models. CT and CTA series earth leakage toroidal current transformers can be used with CT-1S without any problem. 

25 A maximum earth leakage current level on RCR series relays can be increased up to 250 A with CT-1M module. These type transformers allow to protect against extraordinary earth leakages on the instruments which can produce very high current leaks because of its design structure.
