Short Circuit calculation

EA-PSM Electric Short Circuit calculation helps to get immediate results of three-phase, phase-to-phase, phase-to-isolated neutral and phase-to-grounded neutral short circuit currents. Calculations of the module are verified in accordance with IEC 60909 standard.

  • EA-PSM Electric short circuit calculations are fully compliant with IEC and GOST standards, ensuring that short circuit results are accurate and reliable.
  • Helps to solve protection device tripping problems that causes complete system breakdown and because of this manufacturing process or energy supply have to be suspended for a long time.

While calculating Short Circuits you will be able to perform these common tasks:

Equipment sizing Protection coordination Fast and easy documentation
Select appropriate transformers, power lines and other system equipment that can withstand short circuit current before tripping of protection devices. Ensure system protection from overcurrents in order to avoid damage of expensive equipment. EA–PSM allows to export system data and calculation results to Microsoft Office® and AutoCAD®.
