9 Parallel Operation
9.1Principle of Operation
PROTECT 1. has been designed for parallel operation with n+x technology (“n” here stands for the number ofunits required for load supply, “x” for the degree of redundancy)Up. to 3 units of the same type can be connected in parallel here to increase the output power and/or achieve higher availability.
NS Hauptverteilung | MI main distribution |
USV Einspeisung | UPS feed |
Parallelfeld / Handumgehung plus USV | Parallel field / manual bypass plus UPS |
Unterverteilung | subdistribution |
This results in the following constellations with n+x technology:
1 + 0 | Use of 1 unit | max. 10, 15 or | No redundancy |
|
| 20 kVA |
|
1 + 1 | Use of 2 units | max. 10, 15 or | Single redundancy |
|
| 20 kVA |
|
1 + 2 | Use of 3 units | max. 10, 15 or | Double redundancy |
|
| 20 kVA | (max. expansion level) |
2 + 0 | Use of 2 units | max. 20, 30 or | No redundancy |
|
| 40 kVA |
|
2 + 1 | Use of 3 units | max. 20, 30 or | Single redundancy |
|
| 40 kVA | (max. expansion level) |
3 + 0 | Use of 3 units | max. 20, 30 or | No redundancy (max. |
|
| 40 kVA | expansion level) |
