What is EMTP®?

Electromagnetic transients program (EMTP®) is the reference for EMT simulations and analysis of power systems. With its unique capabilities and accuracy,
EMTP® is the industry's fastest, most accurate and most stable software.

• Load-Flow
  EMTP® has a very powerful unbalanced multi-phase load-flow
  solver capable of solving very large scale
  transmission and distribution grids, cases with more than
  300000 buses can be solved.
• Time-Domain
  EMTP® provides the most accurate,
  numerically stable, and consistent time-domain
  EMT simulations.
• Steady-State
  The electrical network equations are solved using
  complex phasors. This option can be used in the stand-alone
  mode or for initializing the time-domain solution.
  A harmonic steady-state solution can be achieved.
• Frequency-Scan
  A frequency scan simulation is available
  with EMTP® to determine the system impedance
  and to identify any possible resonance frequencies
  within the system.

Why Choose EMTP®?

During the time-domain simulations, several challenges can be met.
Here is how EMTP® answers them.

User-friendly GUI

Easy to use, it has a hierarchical architecture based on
subcircuit and it can handle very large grids.

Completely Scriptable

Everything that can be done by hand can be
automated by scripts!

Computational Engine

It significantly improved solution methods for nonlinear models.
Easily solve wide range of problems from load-flow to very fast transients.

ScopeView

ScopeView is a data display tool for visualizing
and analyzing results of EMTP® simulations.

EMTP® Modules

EMTP® allows you to simulate fast to very fast electromagnetic transients.
