The RET-TN unit allows to scale a three-voltage system at the output of RETOM-51 (RETOM-41M) with transformation coefficients of 0,1; 1; 5.

The user also acquires the following abilities:

  • to test the electricity meters with the voltage of 380 V,
  • to test a wide range of AC relays with the voltage of 380 V in distributive networks,
  • to test the blocking devices which blocks a protection at AC voltage circuits breakage by way of simultaneous supply of “star” and “open triangle” voltage circuits,
  • full-scale testing of relay protection devices by means of re-production of faults recorded in COMTRADE format.
