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.
Speed
EMTP® uses sparse matrices to solve very large grids efficiently. Parallel EMT solver is available.

Accuracy
EMTP® uses a fully iterative solver to solve nonlinear models as well as control systems with algebraic loops.
Initialization
No need to waste your time with lengthy initialization process. The network is initialized right at the start of the simulation.
Numerical Stability
A combination of trapezoidal and Backward Euler methods eliminate numerical oscillations that may occur at discontinuities.
