SELECTY - Customer Case Study

The design, sizing, and regulation of the protection system are still one of the major challenges for the integrity and continuity of operation of the power system despite the continuous technology evolution. Protection system shall be capable to continuously monitor the power system, operate quickly and selectively under hundreds of transitory conditions for any type of fault without false trips with the objective to minimize outages, improve safety, and maximize service continuity. This presentation covers a real case study for an expansion of a brownfield industrial installation with new equipment that prompted the need for modification of existing protective device settings thus, requiring revision and re-validation of the coordination studies. The case study will demonstrate how ETAP software features and capabilities were utilized to verify the new / recommended settings to address the protection & coordination objectives and arc flash hazard impact.
