Introduction to Etap

ETAP is the most comprehensive analysis platform for the design, simulation, operation, and automation of generation, distribution, and industrial power systems. ETAP is developed under an established quality assurance program and is used worldwide as a high impact software. ETAP is completely localized in four languages with translated output reports in six languages.

As a fully integrated enterprise solution, ETAP extends to a Real-Time Intelligent Power Management System to monitor, control, automate, simulate, and optimize the operation of power systems.

    it was very informative !
    as an engineer I think one interesting and useful option of power system softwares is their ability to import or export data from or to an other software such as digsilent or MATLAB !
    maybe it would be very useful to everyone!
    thank you for your best website!
