Hi Jack,
As per my understanding you want to design a "three-phase" variable load in Simulink using the Signal Builder/Editor Block. As per the MathWorks Documentation the "Signal Builder" block is outdated, and we can do the design using a "Signal Editor" block. Please refer to the steps below for the implementation:
- Setting Up the Three-Phase Load Model: Place a "Three-Phase" Source block in the blank Simulink model. Use "RLC branches" for the load (available in Simscape>Electrical>Specialized Power Systems>Passives) and configure these elements to represent the desired load in either series or parallel.
- Use the Signal Editor for Variable Load Control: Add a "Signal Editor" block to the model. Open the GUI of the block by double clicking on it and define the signal that represent the different load conditions over time for the variable load along with the signal properties.
- Connecting signal to Control Load Parameters: To dynamically control your load parameters with the signals from the Signal Editor, use blocks like "Gain" to adjust the signal properties. Run the simulation after setting the Simulation parameters and use the visualization block like "Scope" to observe the three-phase load under variable conditions.
Please refer to the MathWorks Documentation for further understanding of the blocks:

Hope this helps!
