EMTP-RV (EMTPWorks) 4.3.1 EMTP Software Introduction
EMTP, which stands for ElectroMagnetic Transients Program, is a powerful and widely used simulation tool designed for the analysis of electromagnetic transients in power systems. It allows engineers to model, simulate, and analyze transient phenomena such as lightning surges, switching operations, faults, and other disturbances that affect electrical networks.

Over time, several versions and graphical interfaces have been developed to improve usability and performance. Some of the notable ones include:
- ATP (Alternative Transients Program)
- ATPDRAW
- EMTP Works
- EMTP-RV
The most recent and advanced version is EMTP-RV , which offers significant improvements in terms of speed, user interface, and modeling capabilities compared to older versions like ATPDRAW and EEUG (European EMTP Users’ Group).
The story of the development of EMTP-RV:
EMTP-RV (ElectroMagnetic Transient Program) is the end result of the “EMTP restructuring project” undertaken by the DCG in 1998 for modernizing the EMTP96 software. In order to rationalize the development of the program, the EMTP Development Coordination Group (DCG) was founded in 1982. At present, North American members of DCG include American Electric Power service corporation (AEP), Centre for Energy Advancement Through Technological Innovation (CEATI), Hydro One Networks and Hydro-Québec.
DCG members outside North America include CRIEPI (Central Research Institute of Electric Power Industry) from Japan and Electricité de France (EDF).
EMTP-RV (EMTPWorks) 4.3.1 Overview of EMTP-RV
EMTP-RV , standing for ElectroMagnetic Transients Program – Restructured Version, represents a complete redesign of the original EMTP software. This version includes over 5,000 bug fixes, improved algorithms, and a modernized graphical user interface (GUI), making it more efficient and user-friendly.
EMTP-RV is especially effective at simulating transient states in complex electrical systems with high precision. It has become a preferred choice among power system engineers due to its robustness and accuracy in modeling fast and slow transients.
However, despite its strengths, EMTP-RV currently lacks built-in tools for database management and handling duplicate data during post-processing tasks—particularly in insulation coordination studies. Therefore, there is a need for additional programs or modules that can support substation equipment modeling under transient conditions and streamline insulation coordination workflows.
Such enhancements would allow for:
- Rapid modeling of substations under transient conditions
- Efficient insulation coordination studies
- Comprehensive statistical analysis of results
- Integration with external tools for advanced data processing
EMTP-RV (EMTPWorks) 4.3.1 Key Features of EMTP Software
- Comprehensive Example Library
The software comes with a wide range of built-in examples, helping users learn and apply the program effectively across different scenarios. - Graphical Output Visualization
Results can be viewed using Scope View, an integrated waveform viewer. Additionally, plot outputs can be exported to AutoCAD, enabling seamless integration into engineering drawings and documentation. - Multi-Platform Data Export
Simulation results can be exported in various formats compatible with other environments such as MATLAB, enhancing cross-platform analysis, validation, and further processing. - Improved Performance and User Interface
Compared to earlier versions, EMTP-RV provides faster simulation execution and a modern, intuitive graphical interface that simplifies model creation and analysis. - Unified Circuit Modeling
The software uses the EMTP Works GUI, generating a single.NET LIST
file for circuit descriptions. This streamlines the simulation setup and ensures consistency across models.
EMTP-RV (EMTPWorks) 4.3.1 System Requirements
To ensure smooth operation and optimal performance when using EMTP software, particularly EMTP-RV, the following system specifications are recommended:
- Operating System : Windows 10 (64-bit only)
- Processor : Intel Core i7 (recommended), Intel Core i5 (minimum acceptable)
- Memory : Minimum 8 GB RAM, 16 GB or higher recommended
- Display Resolution : At least 1920 x 1080 pixels (higher resolutions are supported)
- For best compatibility, display scaling should be set to 100%. Higher scaling values may require resolution adjustments within the software settings.
EMTP-RV (EMTPWorks) 4.3.1 Conclusion
EMTP-RV is a state-of-the-art simulation platform for analyzing electromagnetic transients in electrical systems. With its powerful computational engine and enhanced graphical interface, it supports detailed modeling and high-speed simulations. However, further development is needed to integrate advanced tools for insulation coordination and database handling, providing comprehensive solutions for substation design and protection analysis.
By leveraging its export capabilities and compatibility with platforms like MATLAB and AutoCAD, EMTP-RV remains an essential tool for power system engineers involved in transient analysis, system protection, and equipment design.
