RET-TN
the device for three-phase voltage transformation
- Delivery RET-TNin stock
- Price on-demand
The RET-TN unit allows to scale a three-voltage system at the output of RETOM-71/61/51 (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.
