Electromagnetic Transients Program

ETAP eMT™ offers a dedicated Electromagnetic Transients Program (EMT) for the simulation and analysis of power system transients. ETAP eMT provides an accurate and intuitive analysis software based on trusted EMT simulations powered by PSCAD's EMTDC engine. eMT is a simulator of AC power systems, low voltage, power-electronics, high-voltage DC transmission (HVDC), flexible AC transmission systems (FACTS), distribution systems, and complex controllers. When necessary, ETAP eMT integrates with ETAP's Transient Stability program to offer eMTCoSim™ - CoSimulation of Electromagnetic Transients and Phasors to collectively solve large, complex, and multi-disciplinary system models with higher fidelity.

eMT™ Unlimited Package

eMT software is a value-added feature to ETAP solutions and offered in two versions to simulate small to large networks. eMT Pro Unlimited version offer the following capabilities: 

• eMT™ Electromagnetic Transient Program - Professional License 
• Unlimited Node with 8 Parallel Simulations*
• eMTCoSim™ CoSimulation of Electromagnetic transients & phasors (requires transient stability module) 
• ETAP – PSCAD One-way Data Exchange Interface 

 eMT™ 200 Package

This version is perfect for simulating small systems and co-simulation studies. eMT 200 is fully featured and restricted to network size of 200 nodes (Note: control systems do not contribute to the node count). 

• eMT™ Electromagnetic Transient Program - Professional License  
• Total of 200 Nodes with 8 Parallel Simulations*
• eMTCoSim™ CoSimulation of Electromagnetic transients & phasors (requires transient stability module) 
• ETAP – PSCAD One-way Data Exchange Interface   *Parallel Simulations  The parallel simulations feature permits projects to be run over multiple computer cores simultaneously, resulting in significantly faster results than when run in series over a single core. Parallel computing feature can be expanded to 16, 32, and 64 Cores as an option.
