7.2.3.2 Showing the graph in °C
When the resistance of the winding at any specific temperature and the material is known, all the
values can be displayed as °C.
Enter the resistance value (Rcold) of the
winding, the corresponding temperature (Tref)
and the temperature coefficient of the
conductor.
The approximation and the values are shown as Temperature.
Linear Approximation:
T0:
Temperature at time t = zero
m:
Slew rate dt/dt in °/ min
Cor: Correlation of the approximation
Exponential Approximation:
T0:
Temperature at time t = zero
R∞:
Temperature at time t = ∞
tau:
Time constant
Cor:
Correlation of the approximation
