Welcome to the web page of ATPDraw

 

ATPDraw is a graphical, mouse-driven preprocessor to the ATP version of the Electromagnetic Transients Program (EMTP) on the MS-Windows platform. In ATPDraw the user can construct an electrical circuit using the mouse and selecting components from menus, then ATPDraw generates the ATP input file in the appropriate format based on "what you see is what you get". The simulation program ATP and plotting programs can be integrated with ATPDraw. A license is required to download and use the solver ATP. This can be obtained from https://www.atp-emtp.org

This web-site has been in operation since 2012. Users can register with email authentication by passing a CAPTCHA and an EMTP quiz. The web-site offers discussion forums with nested discussions, images/document uploads and search functionality. By registering on this web-site users also get access to latest ATPDraw downloads (NOT the solver tpbig.exe). Upload of Cases from users at this web-site is supported from April 19, 2022.
