grid protection sets
Here are grid protection sets with tie breakers for different installed loads of decentralized customer generation plants. Grid and plant protection changetec BISI according to VDE-AR-N 4105 and grid monitoring changetec BISI according to VDE 0126-1-1/A1. The changetec BISI according to VDE 0126-1-1/A1 is for all decentralized customer generation plants, like PV systems, wind turbines, BTTP, own consumption systems and hydropower plants <30KW and it is permissible for all nations, where VDE 0126-1-1 and VDE 0126-1-1/A1 are still determining, for example Austria. The changetec BISI according to VDE-AR-N 4105 is basically suitable for all decentralized customer generation plants, which feed into the low-voltage grid.
