The traditional solutions for protecting networked distribution lines, sub-transmission lines, and industrial facility incoming supply lines use some form of pilot protection. A significant challenge for pilot protection, especially in retrofit situations, is the cost of installing pilot communications channels. Digital radio is an inexpensive method to provide digital communications for pilot protection at the distribution level. Digital radio has the ability to send permissive, blocking, and transfer trip signals over short to medium distances. Relay to relay messaging protocols have now become standardized through the IEC61850 GOOSE profile and can provide not only protection information but also metering, monitoring, and control.

Time based coordination and protection is the normal basis for coordinating low voltage power distribution systems. Enhancements, such as zone selective interlocking and bus differential protection, may be used to accelerate protective devices. However, these improvements may be costly, difficult to implement, and may not function as expected using commonly available technology. Nevertheless, the potential benefit of fault clearing speed and selectivity are more valued in todaypsilas arc-flash and reliability conscious environment than ever before. The writers shall discuss some issues associated with these traditional improvements, pitfalls to avoid and, more effective ways to implement zone-based protection to achieve fast fault protection while maintaining complete selectivity for a broad range of fault magnitudes, system configurations and load types.
