1. Positioning and objective
The aim of the test “ Working point – Sine wave – Generator – RLN” is to characterize the generator performance when operating with a starconnected 3phase R, L load at the targeted speed N.


“Working point – Sine wave – Generator – R, L, N ” illustration 
The results of this test give an overview of the electromagnetic analysis of the machine considering the machine topology.
The general data of the machine, like machine constants, power balance and magnet behavior are computed and displayed. The considered convention is the generator one.
The magnetic flux density is also computed in every region of the machine magnetic circuit to evaluate the design.
The following table helps to classify the test “Working point – Sine wave – Generator – R, L, N”.
