Impedance computation - Auto

Overview

The aim of this section is to compute the inter bar and inter pole impedance of the damper circuit end rings.

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.
