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.
