Only high-quality test of electrical equipment!

In 2016 RETOM-21 was modified in a number of ways:

  • the weight of the test device was reduced for 7 kg;
  • the accuracy of the output data settings was increased by 10 times;
  • the maintenance of the equipment became even easier thanks to the new layout of controls: all the elements and programming module indicators are accessible in a single window;
  • the Source 3 can be controlled via PC;
  • programming module “Current Transformer” employs a wider range of the excitation curve in automatic mode(up to 2000 V), which allows users to promptly check CT with the knee point of an excitation curve up to 1800 V;
  • additionally, demagnetization of transformers is made automatic, which provides an adequate functioning of the protective relay;
  • software design and interface were updated, making the latter more friendly and intuitive. The software can be used by specialists with no prior experience and qualifications.

All these modifications allowed to improve the usability of the equipment.

RETOM-21 is a basic device of the testing system intended for testing of primary and secondary electrical equipment. Technical data:

  • max. output current of up to 800 A;
  • max. output voltage of up to 500 V;
  • sustainable maximum power up to 2500 and 4500 VA respectively;
  • adjustment of current, voltage, frequency, phase (angle);
  • multimeter allows to measure current, voltage, frequency and phase;
  • auxiliary DC power source;
  • full-featured CT maintenance check etc.

RETOM-21 is a certified measuring equipment.
