Etap Version 22 [top] Review
Expanded data for Star Protection and Selectivity analysis.
The Star module in ETAP 22 includes an automated rule-based evaluation engine. It automatically suggests time-overcurrent relay settings based on the upstream and downstream equipment constraints, significantly reducing manual TCC (Time-Current Characteristic) curve plotting time. Ground Grid Design etap version 22
While version 21.0 set a strong foundation with its integrated analysis modules and early Arc Flash features based on Australian standards, ETAP 22 represented a major generational leap. The newer version added entirely new classes of analysis (Flicker, Lightning Risk, Grid Code compliance), dramatically expanded safety standards (IEC, German DGUV), and introduced the eLabelMaker. It also offered a more polished user interface and a greater emphasis on automation and renewable energy, making it a much more comprehensive tool for engineers dealing with the modern, decarbonized grid.

Energy storage is vital for mitigating the intermittent nature of renewables. ETAP 22 features advanced BESS sizing and allocation tools. Users can simulate charging and discharging cycles based on electricity market pricing, peak-shaving requirements, or islanded microgrid needs. The software analyzes the thermal behavior and degradation of batteries over time, providing a more accurate return-on-investment (ROI) calculation for capital-intensive storage projects.
