Transmission Protection Software

Combine the power of ETAP Star & ETAP StarZ with the most comprehensive Arc Flash Hazard analysis for an integrated transmission protection software for transmission and sub-transmission systems.

ETAP Star provides intelligent tools and powerful capabilities to analyze system protection and troubleshoot false trips, relay and breaker mis-operation, mis-coordination.

ETAP StarZ expands the protective device capabilities to include sliding fault analysis and detailed Distance relay (21) modeling for generator and line protection.
