Flux saturation
This module integrates the voltage to obtain the flux time-function and determines the
magnitude of the flux.
Figure 3-93: Principal scheme of the flux calculation
The inputs are the sampled values of a line-to-line voltage (ULL).
The output is the magnitude of the flux (FluxMagn), internal signal.
Characteristics
This module calculates the required time delay based on the magnitude of the flux and the
parameter settings.
Decision logic
The decision logic module combines the status signals to generate the trip command of the
function.
