Smart electrical software tools

PowerStar and PowerNet are similar software tools with identical user interface and same features:

Powerful Capable of simulating multi-voltage power generation and distributionsystems. Both software can be used to analyze existing electrical systems or new electrical system design project . Great for testing what-if scenarios.

Flexible Both will handle imperial or metric units, 50 or 60 hz, low voltage to extra high voltage. PowerStar will calculate any combination of single phase and three phase loads. PowerNet will calculate line to ground short , double line and three phase to ground short circuit. And more...

Easy to use Create circuits in minutes using common windows actions like cut, copy, paste and mouse drag, drop and clicks. After calculation, simply mouse over any symbol in PowerStar or PowerNet to display electrical data, voltage and current vectors.

Affordable Get all the capabilities and features of high end software for the cost of many software that does little more than cable sizing and voltage drop calculations. PowerStar and PowerNet cost only a fraction of similar electrical engineering software. Both are now heavily discounted, but not for long.
