## What is power grid calculator?

Now you can calculate electrical systems easily, quickly and without having to collect formulas. Directly in the system with your smartphone. Everything is displayed clearly and easily understandable.

You can see and evaluate all data for two voltage levels at the same time.

Here is an excerpt of the important data that the app processes for you.

apparent power
real power
reactive power
voltages
currents
angle
power factor
energy flow
performance triangle
delta- and star-connection
inductors
capacities
....

Don't make your work unnecessarily difficult, use the app whenever you need to know something.
