UTA 210

It is an advanced tool designed to perform accurate measurements of all relevant Current Transformer (CT) parameters in order to compare them with the requirements established by IEC or IEEE standards. This tool plays a crucial role in checking the compliance and performance of TCs, ensuring that they meet international quality and safety standards.

It is the first device with such features:

  • Ratio (up to 10000:1);

  • ​Current ratio error and phase error for all measurement points defined in the selected standard;

  • Winding resistance;

  • Excitation/saturation voltage current;

  • Secondary load;

  • Saturated inductance (Ls);

  • Unsaturated inductance (Lm);

  • Remanence flow factor (Kr);

  • Secondary time constant (Ts);

  • Instrument safety factor (FS/FSi);

  • Sizing factor according to class PX, TPS (Kx);

  • Accuracy limiting voltage/current according to PX class (Ek / Ie);

  • Turn ratio according to class PX (N);

  • Turn ratio and compound error (εt,εc);

  • Nominal symmetric short-circuit current factor (Kssc);
