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®.|
