Press “Analyse”
You’ll be asked for the “Approximation” Model to
calculate the value of the Winding at time =
zero.
Select the Approximation Model:
Exp (Exponential) or Linear
After selecting the Model press “Analyse”
The value and the graph of the approximation
R(t=0) is shown.
Linear Approximation:
R0:
Winding Resistance at time t = zero
m:
Slew rate dr/dt in %/ min
Cor: Correlation of the approximation
Exponential Approximation:
R0:
Winding resistance at time t = zero
Rinf:
Winding resistance at time t = ∞
tau:
Time constant
Cor:
Correlation of the approximation
