Automatic computation mode
When automatic computation mode is set, inter bar and inter pole end-ring impedances
are computed by internal processes. They are determined for the synchronous
operation of the machine, meaning that there is no slip between the rotor and the
stator. The temperature at the end ring (at Connection Side and Opposite Connection
Side), and the material of the end ring are considered for the internal calculation
process.
Note: Even if bars are not evenly distributed,
only an average value is provided for the inter bar impedance based on the
average distance between the bars.
