Wiring schematics for different markets and system types
The following wiring scenarios help ensure proper installation of NA Schutz for different system configurations and market requirements:
- Scenario 1: Single or multi-rack without LVRT
Short for "low voltage ride through". LVRT is the ability of an electrical device - typically a wind turbine or solar inverter - to stay connected to the grid during short periods of low voltage, such as those caused by faults or disturbances. The purpose is to support the grid by remaining online and helping restore normal conditions. requirement:
- Denmark DK1 Type A up to 125 kW (TF331).
- Denmark DK2 Type B up to 125 kW (TF331).
- Sweden Type A up to 1.5 MW (EIFS:2018).
- Netherlands up to 1 MW (Regulering 20).
- Scenario 2: Single or multi-rack with LVRT requirement:
- Germany (VDE 4105).
- Scenario 3: Multi-rack with LVRT requirement:
- Denmark DK1 Type B from 125 kW and up to 3 MW (TF331).
- Denmark DK2 Type B from 125 kW and up to 3 MW (TF331).
- Germany (VDE 4110).
Note: When LVRT is required, power the grid protection device using one of the following:
- ABB CP-C.1 24/5.0 (1SVR360563R1001).
- ABB CP-B 24/3.0 (1SVR427060R0300).
