What is EasyPower®?

EasyPower® is a computer-aided engineering tool for the analysis and design of industrial, utility, and commercial electrical power systems. EasyPower is unique in that it completely integrates the short circuit, power flow, protective device coordination and database functions under control of the interactive graphical one-line diagram. EasyPower lets you work like you normally do—directly from the one-line. EasyPower has an interactive, user-friendly interface designed for efficient and accurate power system analysis.

EasyPower uses the latest network analysis techniques developed by world leaders in sparsity solution algorithms and innovative computer techniques. Our company prides itself in its ingenuity of software development offering a wide variety of algorithms that are not available in other programs. This gives EasyPower a tremendous advantage over other programs in execution time, modeling capabilities, and accuracy.

In addition to the full EasyPower program, there are several smaller programs that include a subset of features targeted for specific uses. These include OneLine Designer™ and ArcFlash Essentials™.

  • OneLine Designer™ includes the powerful one-line creation features of EasyPower, but without the full analysis capabilities. Use it to create one-lines and enter data about your equipment.
  • ArcFlash Essentials™ includes many of the basic powerful features of EasyPower. Use it to quickly and easily create detailed one-line diagrams, perform arc flash hazard calculations, and maintain system and safety documentation—all in one place.

Note: In this documentation, the term "EasyPower" is used to specifically describe the EasyPower software but also may refer generically to OneLine Designer or ArcFlash Essentials.
