Internal Circuit of the Component

Example Model

This example shows the use of the Sequence analyzer block to compute the three sequence components of a three-phase unbalanced signal.

Note that the following demo requires that users edit the ScopeView template, and replace the existing .oprec data source with the data generated during the simulation.
