Some modules

The ETAP Load Flow Analysis module calculates the bus voltages, branch power factors, currents, and power flows throughout the electrical system. ETAP allows for swing, voltage regulated, and unregulated power sources with multiple power grids and generator connections. It is capable of performing analysis on both radial and loop systems. ETAP allows you to select from several different methods in order to achieve the best calculation efficiency.–
The ETAP Short-Circuit Analysis program analyzes the effect of 3-phase, line-to-ground, line-to-line, and line-to-line-to-ground faults on electrical distribution systems. The program calculates the total short circuit currents as well as the contributions of individual motors, generators, and utility ties in the system. Fault duties are in compliance with the latest editions of the ANSI/IEEE Standards (C37 series) and IEC Standards (IEC 60909 and others).
Star is a fully integrated system protective device coordination and selectivity module within ETAP. Star offers the state-of-the-art tool for performing device coordination, protection, and testing. This is achieved by utilizing intelligent one-line diagrams, comprehensive device libraries, and an integrated multi-dimensional database. Star enables power engineers to easily and efficiently perform protective device coordination studies. The built-in intelligent features provide informed and reliable recommendations regarding the feasibility of the devices under consideration. Engineers can quickly realize possible design issues and make informed decisions to improve system reliability, increase system stability, and boost financial savings.
