Multi-range Reference Electronic Current Transformer EMT-100

Sphere of application

EMT-100 is a reference transformer that converts AC current on its input into output AC voltage.

It can be applied as part of test and calibration setups within metrological and industrial test labs, certification bodies etc.


In AC measurements, EMT-100 replaces a set of reference shunts 0.1; 0.5; 1; 5; 10; 20; 50; 100 А and offers the following advantages over the shunts:

  • Current measuring ranges are switched automatically (except for the 100A range);
  • Overload protection.
