Description

Protective relay testing device UPZ –450/200 is used for:

1. Adjustment and testing of simple protective relays in place of their installation at power plants, substations, industrial plants or in the laboratory;
2. Adjustment and testing of electro-automatic elements (electromagnetic relays, contactors, motor starters, etc.);
3. Adjustment and testing of circuit breakers.

• Output voltage:
  • Range of output AC sinusoidal voltage formed by device is divided into three sub ranges:
    • 0 – 50 (V);
    • 0 – 250 (V);
    • 0 – 450 (V).
  • Range of output DC rectified voltage generated by device is divided into three sub ranges:
    • 0 – 50 (V);
    • 0 – 250 (V);
    • 0 – 450 (V).
• Output current:
  • Range of output AC sinusoidal current formed by device is divided into two sub ranges:
    • 0 – 20 (A);
    • 0 – 200 (A);
•  Complementary:
  • Tripping time interval meter                                                                       0 – 9999.9 sec
  • Tripping time interval measurement accuracy, max                                   0.2 msec
  • Tripping time interval measurement resolution                                          0.1 msec

UPZ-450/200 tester is housed within a single enclosure, which creates additional convenience during the use. It
includes connecting wires and cables, to connect the tested objects.
