This work package aims at utilizing a digital substation and wide-area environment (providing more real-time information and observability due to more sensors) to improve protection and fault location schemes, particularly in complex, multiple-fault cases. A main focus of the WP is on the special challenges of ground faults in isolated or resonance grounded systems. Topics of interest in this WP are:

• Detection and location of ground-faults in isolated or resonance grounded systems.
• Fault location using distributed sensors and wide-area strategies
• Protection and fault handling  in complex fault situations, with possibly multiple faults
• Utilization of the increased system observability for adaptivity of protection settings
• Communication, self-healing, transient based protection
