Figure 6. Line differential protection for an interconnecting feeder between two primary distribution substations using standard configuration
A
Figure 6 illustrates line differential protection for an
interconnecting feeder between two primary distribution
substations using standard configuration A. Additionally,
protection is offered for a in-zone power transformer, when
available and located in the protection zone.
