1.1.3 How is the apparent effekt "S" of a støbejern trefaset motor calculated?

Here's an example:

A 400 volt trefaset motor has a rated current of 129.9 amperes and a current draw of 129.9 amperes.
What apparent effekt result fra this information?

S = U x I x √3
S = 400V x 129.9A x √3
S = 90kVA

Units of measurement:

Apparent effekt S = kilovolt-amperes [kVA]
Spænding U = Volt [V]
Current I = Ampere [A]
√3 or 1.73 = uden
