Fault on relay protection bus

Short-circuit faults on buses can be isolated by allowing remote substation breakers on all lines that feed into the faulted bus to trip by Zone 2 or time-delay ground relay. This type of bus protection is simple and the most economical. For substations with terminals capable. Differential protection provides high speed fault-clearing necessary for critical busbars such as transmission busbars, or distribution busbars where arc flash hazards are a concern. [pdf]
