The simulation of power systems transients has never been so easy!

EMTP^® is the most complete and technically advanced software for simulation and analysis of power systems.

• EMTP^® is the reference for the simulation of electromagnetic and electromechanical EMT transients. It is known to be the fastest, the most accurate and the most numerically stable time-domain software in the industry.
• Control systems and protections can be modelled in detail using the complete libraries of components.
• EMTP^® has a powerful unbalanced multi-phase load-flow capable of solving very large scale transmission and distribution grids, cases with more than 300 000 buses can be solved by our EMT solver.
• EMTP^® has the most user-friendly graphical interface and load-flow, steady-state and time-domain simulations using the same grid data and within the same environment.
• EMTP^® is completely scriptable. EVERYTHING that can be done by hand can be automated by scripts!
• EMTP^® uses dynamic memory allocation and can simulate arbitrary topology networks without any user intervention: what you draw is what you simulate!
