Description
Protective relay testing device UPZ –450/3000 is used for:
- Adjustment and testing of simple protective relays in place of their installation at power plants, substations, industrial plants or in the laboratory;
- Adjustment and testing of electro-automatic elements (electromagnetic relays, contactors, motor starters, etc.);
- 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).
- Range of output AC sinusoidal voltage formed by device is divided into three sub ranges:
- Output current:
- Range of output AC sinusoidal current formed by device is divided into two sub ranges:
- 0 – 20 (A);
- 0 – 200 (A);
- Test range of circuit breakers: 0 – 3000 A
- Range of output AC sinusoidal current formed by device is divided into two sub ranges:
- 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-450/3000 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.
