Welcome to EEUG, users group of ATP-EMTP

 Please note September 2022: EEUG got new executive board, see news-box right

This site has been established for the users of the royalty-free ATP version of the Electromagnetic Transients Program (EMTP). The ATP license is free for nearly everyone and requires only that you agree to the licensing terms. Licensing forms and information about ATP and EEUG are also available here. Services provided by EEUG to the new members and/or ATP users having been licensed by EEUG are also accessible via this site.

ATP is a universal program system for digital simulation of transient phenomena of electromagnetic as well as electromechanical nature. With this digital program, complex networks and control systems of arbitrary structure can be simulated. ATP has extensive modelling capabilities and additional important features besides the computation of transients. It has been continuously developed through international contributions over the past 30+ years.

It seems you are in the public area. There are other additional areas, licensed and member. The visible content is adapted to your login accordingly.

To become licensed, please don't mind to request a licensed using "How To ---> be licensed" menu

To become a member of EEUG please use the form choosing "How to --> Become EEUG member" menu.



in September 2022, EEUG restarted physical conference and meeting at University Mannheim, hosted by Prof. Thomas Unger, Gunter Lichtenberger and their team.

the new executive board in names:

Chairmen Prof. Hans Kristian Hoidalen, 
Norwegian University of Science and Technology

Chairman Prof. Thomas Hunger
Universit├Ąt Mannheim

Treasurer Gunter Lichtenberger, DNV, Germany

Kostas Velitsikakis

DNV Dubai
Harald Wehrend
Univ.of Applied Science Kiel, Germany


please give your trust to the new board in good continuation of EEUG and ATP-EMTP spirit.


In 2021, the following webinars have been offered:

Transient recovery voltage analysis Thi Thu Ha Pham; Schneider Electric

Introduction to modelling of induction machines Delcho Penkov; Schneider Electric

Selection of Generator Circuit-Breaker using EMTP-ATP;  Pryianka Gugale, Hitachi ABB

 HV Cable Technologies Modelling and case of study using ATP-EMTP_A_Mansoldo; DNV-GL

All material can be found at


for licensed users after login



Due to pandemic restrictions European-wide in 2020, EEUG decided, together with out prospected conference host 

Prof. Grigoris Papagiannis and team, School of Electrical & Computer Engineering, Aristotle University of Thessaloniki, Greece

to offer online webinars free of charge for interested licensed users.

See here the preliminary schedule:

About EEUG

IMG 0331            

EEUG "European EMTP-ATP Users Group" is the non-profit association for the users of one of the world wide mostly used program for the simulation of electromagnetic transients in electric power systems, to name only the main application.

The association maintains mailing list for question and answers between all registered and licensed users, organizes conferences and trainings, to name the main benfits.

Using the program requires to be licensed (see: How To --> be licensed), includes no support like members get.

Members of EEUG benefit from comfortable setup-programs, lower rates for materials and conference/training fees, access of course materials after period of time after the courses, and early access to new program features.
