Table 1. List of calibration factors


1 The reference temperature.

First, resistance values are computed by considering a temperature equal to 20°C.

However, the user can also define his own reference temperature to compute the corresponding phase resistance and Line-Line resistance values.
Note: This reference temperature is used only in the winding design environment.

The test temperatures are defined in the test settings (refer to TEST chapter).
2 Reference maximum Line-Line voltage. It allows evaluating the voltage drop between the conductors.
3 Voltage drop limit between 2 superimposed conductors. This limit is given to better visualize the voltage threshold, which shall not be exceeded (see the displaying of colored fields in the table).
4 Setting of the “Resistance factor”. It allows adjusting the computation result of resistance with resistance measurement. Thus, the resulting phase resistance value is considered.
5 Setting of the “Inductance factor”. It allows modifying the computation result of end-winding inductance.

Thus, the resulting end-winding inductance value is considered.
