FEATURE

• Low-impedance busbar protection 

• Stub and T-zone protection 

• High functional reliability due to two independent measurement criteria: 

- stabilized differential current algorithm 

- directional current comparison algorithm 

• Phase-by-phase measurement 

• Reduced CT performance requirements 

• High through-fault stability even in case of  CT saturation 

• Full solid-state busbar replica 

• No switching of CT circuits 

• Only one hardware version for  

- 1 and 5 A rated currents 

- all auxiliary supply voltages between  48 V DC and 250 V DC 

- nominal frequencies of 50, 60 and  16.7 Hz 

• Short tripping times independent of the  plant’s size or configuration 

• Centralized layout: Installation of hardware  in one or several cubicles 

• Distributed layout: Bay units distributed  and, in the case of location close to the  feeders, with short connections to CTs, isolators, circuit breakers, etc. 

• Connections between bay units and central  unit by fiber-optic cables 

- maximum permissible length 1200 m  

- for distributed and centralized layout 

• fiber-optic connections mean interference proof data transfer even close to HV power  cables 

• Replacement of existing busbar protection  schemes can be accomplished without restrictions (centralized layout) in the case of  substation extensions e.g. by a mixture of  centralized and distributed layout 

• Easily extensible
