A RAPID METHOD FOR DETERMINING THE NET
POWER OF AN ASYNCHRONOUS MACHINE
This work presents a method to rapidly determine the net power of an
asynchronous machine running as a motor. For this we read a minimal set of
engine speed values, excitation winding current values, power factor values
when we know the nominal values of the tested engine. The find the net power
values we use the phases in drawing up the circle diagram for an electrical
machine. This method can easily used to find the electric energy balance of
various industrial units.
