Basler Solutions for
Bus Protection

Need a Faster Way to Clear Bus Faults —
Need Fewer Overlapping Zones of Overcurrent Protection

Has your facility performed an arc flash analysis of your switchgear and found that you need a faster way to clear bus faults?

Þ

High impedance bus protection is the fastest scheme available, and interlocked feeder-main protection is a fast scheme that requires no new CTs.

Does your facility have too many overlapping zones of overcurrent protection and hence you cannot achieve good relay coordination?

Þ
 

Interlocked feeder-main relaying and partial differential CT wiring can remove one level of overcurrent protection.
